The Future of Electronics is Light

By: Arnab Hazari, University of Michigan

ElectronicsFor the past four decades, the electronics industry has been driven by what is called “Moore’s Law,” which is not a law but more an axiom or observation. Effectively, it suggests that the electronic devices double in speed and capability about every two years. And indeed, every year tech companies come up with new, faster, smarter and better gadgets.

Specifically, Moore’s Law, as articulated by Intel cofounder Gordon Moore, is that “The number of transistors incorporated in a chip will approximately double every 24 months.” Transistors, tiny electrical switches, are the fundamental unit that drives all the electronic gadgets we can think of. As they get smaller, they also get faster and consume less electricity to operate.

In the technology world, one of the biggest questions of the 21st century is: How small can we make transistors? If there is a limit to how tiny they can get, we might reach a point at which we can no longer continue to make smaller, more powerful, more efficient devices. It’s an industry with more than US$200 billion in annual revenue in the U.S. alone. Might it stop growing?

Getting close to the limit

At the present, companies like Intel are mass-producing transistors 14 nanometers across – just 14 times wider than DNA molecules. They’re made of silicon, the second-most abundant material on our planet. Silicon’s atomic size is about 0.2 nanometers.

Today’s transistors are about 70 silicon atoms wide, so the possibility of making them even smaller is itself shrinking. We’re getting very close to the limit of how small we can make a transistor.

BacteriaBy using mild electric current, a team of researchers from Washington State University has demonstrated the ability to beat drug-resistant bacterial infections – a technology with the potential to treat chronic wound infections.

Lead by ECS member Haluk Beyenal, the team combined an antibiotic with electrical current to kill the highly persistent Pseudomonas aeruginosa PAO1 bacteria. That very same bacteria can seen in infections of the lung, cystic fibrosis, and even chronic wounds.

“I didn’t believe it. Killing most of the persister cells was unexpected,” Beyenal says. “Then we replicated it many, many times.”

The 21st century has brought new light to strains of antibiotic-resistant bacteria. In many cases, this bacterial resistance is caused by the widespread use of antibiotics in the 20th century. According to the Centers for Disease Control, at least 23,000 deaths per year are attributed to antibiotic-resistant bacterial infections.

Grace Hopper

Two female tech pioneers won the Presidential Medal of Freedom. Grace Hopper, known as the “first lady of software,” and Margaret Hamilton, regarded for her leadership role in a NASA software team that helped land a man on the moon, continued to break the glass ceilings in computer science upon receiving this prestigious award.

Hopper was one of the first programmers of the Harvard Mark I and a pioneer in computer science until she passed away in 1992.

When discussing Hopper’s achievements, U.S. President Barack Obama said, “If Wright is flight, and Edison is light, then Hopper is code.”

Margaret Hamilton

Margaret Hamilton

Hamilton played a major role on the 1960s NASA team that got a man to the moon. She was critical in developing the on-board flight software for the Apollo space program.

President Obama said, “Luckily for us, Margaret never stopped pioneering. She symbolizes that generation of unsung women who helped send humankind into space.”

From cellphones to cyber command, the work of these women has helped shape the world we currently live in.

Editors' ChoiceThree new Editors’ Choice articles have been published recently in the Journal of The Electrochemical Society (JES) and ECS Journal of Solid State Science and Technology (JSS).

An Editors’ Choice article is a special designation applied by the Journals’ Editorial Board to any article type. Editors’ Choice articles are transformative and represent a substantial advance or discovery, either experimental or theoretical. The work must show a new direction, a new concept, a new way of doing something, a new interpretation, or a new field, and not merely preliminary data.

According to scientists at the University at Buffalo, a new glowing dye called BODIPY could be a central part of the liquid-based batteries that researchers are looking at to power our cars and homes.

BODIPY – or boron-dipyrromethene – is a fluorescent material that researchers believe could be an ideal material for stockpiling energy.

While the dye is fluorescent, that’s not what initially attracted scientists. According to new research, the dye has chemical properties that enables it to store electrons and participate in electron transfer. These two properties are critical for energy storage.

The new research shows that BODIPY-based batteries operate efficiently and display promising potential for longevity, functioning for more than 100 charge cycles.

“As the world becomes more reliant on alternative energy sources, one of the huge questions we have is, ‘How do we store energy?’ What happens when the sun goes down at night, or when the wind stops?” says lead researcher Timothy Cook, ECS member and assistant professor of chemistry at the University at Buffalo. “All these energy sources are intermittent, so we need batteries that can store enough energy to power the average house.”

InSeNewly developed semiconductor materials are showing promising potential for the future of super-fast electronics.

A new study out of the University of Manchester details a new material called Indium Selenide (InSe). Like graphene, InSe if just a few atoms thick, but it differs from the “wonder material” in a few critical ways. While graphene has been hailed for its electronic properties, researchers state that it does not have an energy gap – making graphene behave more like a metal than a semiconductor.

Similarly, InSe can be nearly as thin as graphene while exhibiting electronic properties higher than that of silicon. Most importantly, InSe has a large energy gap, which could open the door to super-fast, next-gen electronic devices.

2016 is set to be the world’s hottest year on record. According to the World Meteorological Organization’s preliminary statement on the global climate for 2016, global temperatures for January to September were 0.88°C above the long-term (1961-90) average, 0.11°C above the record set last year, and about 1.2°C above pre-industrial levels.

While the year is not yet over, the final weeks of 2016 would need to be the coldest of the 21st century for 2016’s final number to drop below last year’s.

Record-setting temperatures in 2016 came as no real surprise. Global temperatures continue to rise at a rate of 0.10-0.15°C per decade, and over the five years from 2011 to 2015 they averaged 0.59°C above the 1961-1990 average.

Giving temperatures a further boost this year was the very strong El Niño event of 2015−16. As we saw in 1998, global temperatures in years where the year starts with a strong El Niño are typically 0.1-0.2°C warmer than the years either side of them, and 2016 is following the same script.

Almost everywhere was warm

Warmth covered almost the entire world in 2016, but was most significant in high latitudes of the Northern Hemisphere. Some parts of the Russian Arctic have been a remarkable 6-7°C above average for the year, while Alaska is having its warmest year on record by more than a degree.

Almost the whole Northern Hemisphere north of the tropics has been at least 1°C above average. North America and Asia are both having their warmest year on record, with Africa, Europe and Oceania close to record levels. The only significant land areas which are having a cooler-than-normal year are northern and central Argentina, and parts of southern Western Australia.

What’s Next for Batteries

BatteryTwenty-sixteen marked the 25th anniversary of the commercialization of the lithium-ion battery. Since Sony’s move to commercialize the technology in 1991, the clunky electronics that were made possible by the development of the transistor have become sleek, portable devices that play an integral role in our daily lives – thanks in large part to the Li-ion battery.

“There would be no electronic portable device revolution without the lithium-ion battery,” Robert Kostecki, past chair of ECS’s Battery Division and staff scientist at Lawrence Berkeley National Laboratory, tells ECS.

Impact of Li-ion technology

Without Li-ion batteries, we wouldn’t have smartphones, tablets, or laptops – more so, electric vehicles would have a slim chance of competing in the transportation sector and dreams of large-scale energy storage for a renewable grid may be dashed. Without the Li-ion, there would be no Tesla. There would be no Apple. The landscape of Silicon Valley as we know it today would be vastly different.

While the battery may have hit the marketplace in the early ‘90s, pioneers such as Stanley Whittingham, Michael Thackeray, John Goodenough, and others began pushing the technology in the ‘70s and ‘80s.

In its initial years, Li-ion battery technology boomed. As the field gained more interest from researchers after commercialization, developments started pouring in that doubled, or in some cases, tripled the amount of energy the battery was able to store. While progress continued over the years, the pace began to slow. Incremental advances at the fundamental level opened new paths for small, portable electronics, but have not answered demands for large-scale grid storage or an electric vehicle battery that will allow for a drive range of over 300 miles on a single charge.
