Why do synthetic 2D materials often perform orders of magnitude worse than predicted? A new understanding of this scenario could improve the materials’ performance in future electronics, photonics, and memory storage.

2D materials are films only an atom or two thick. Researchers make 2D materials by the exfoliation method—peeling a slice of material off a larger bulk material—or by condensing a gas precursor onto a substrate. The former method provides higher-quality materials, but is not useful for making devices. The second method is well established in industrial applications, but yields low performance 2D films.

The researchers demonstrated, for the first time, why the quality of 2D materials grown by the chemical vapor deposition method have poor performance compared to their theoretical predictions. They report their results in Scientific Reports.

Symposium G01: Semiconductor Wafer Bonding: Science, Technology, and Applications 15

Symposium Focus: The fifteenth symposium solicits original theoretical and experimental papers that document new developments and cover the full range of basic science, process technologies, and product applications of semiconductor wafer bonding (direct, anodic, thermo-compression, eutectic, adhesive bonding). Besides permanent bonding, temporary wafer bonding technique deserves also to be discussed regarding all the recent development in many 3D applications. Fundamental aspects of interest include surface preparations for bonding, film transferring, low temperature bonding, surface activation at bonding interfaces, bonding techniques, novel material composites to synthesize heterostructures. Presentations characterizing currently utilized materials and processes, as well as novel approaches to new materials systems and modeling and process simulations are encouraged. Practical aspects of interest include innovative developments in product architecture and new integration and processing schemes for microelectronics, photonics, MEMS, microtechnologies, nanotechnologies and other relevant applications.

Invited Speakers from CEA-Leti, imec, EVG, KTH, Qromis, and more will be featured during the symposium.

In order to power entire communities with clean energy, such as solar and wind power, a reliable backup storage system is needed to provide energy when the sun isn’t shining and the wind doesn’t blow.

One possibility is to use any excess solar- and wind-based energy to charge solutions of chemicals that can subsequently be stored for use when sunshine and wind are scarce. At that time, the chemical solutions of opposite charge can be pumped across solid electrodes, thus creating an electron exchange that provides power to the electrical grid.

The key to this technology, called a redox flow battery, is finding chemicals that can not only “carry” sufficient charge, but also be stored without degrading for long periods, thereby maximizing power generation and minimizing the costs of replenishing the system.

Symposium H07: Electronic, Thermal, and Electrochemical Properties of Metal Organic Frameworks (MOFs): Technology, Applications, and Emerging Devices

Symposium Focus: The 1st International Symposium sponsored by the Electronics and Photonics Division of the Electrochemical Society brings together researchers in chemistry, materials science, physics, devices and process engineers and related interdisciplinary areas, to seek and capture the state-of-the art in MOF based fundamental aspects and latest technological applications. This symposium offers a new interdisciplinary and international platform, and aims to contribute towards advancing the fundamental understanding of the layered MOF thin films and aiming to improve technological applications thereof. Original contributions are solicited that cover all fundamental and applied aspects including electronic, thermal and electrochemical transport properties and phenomena, device/ system fabrication and integration of MOF thin films into emerging technological device applications. All oral presentations will be grouped into topical sessions. Invited Keynote speakers will present critical reviews covering recent advances and future directions in the diverse field of fundamental and applied MOF properties.

Using advanced computational methods, University of Wisconsin–Madison materials scientists have discovered new materials that could bring widespread commercial use of solid oxide fuel cells closer to reality.

A solid oxide fuel cell is essentially an engine that provides an alternative way to burn fossil fuels or hydrogen to generate power. These fuel cells burn their fuel electrochemically instead of by combustion, and are more efficient than any practical combustion engine.

As an alternative energy technology, solid oxide fuel cells are a versatile, highly efficient power source that could play a vital role in the future of energy. Solid oxide fuel cells could be used in a variety of applications, from serving as a power supply for buildings to increasing fuel efficiency in vehicles.

However, solid oxide fuel cells are more costly than conventional energy technologies, and that has limited their adoption.

Symposium G05: Materials, Formulation, and Processes for Semiconductor, 2.5 and 3D Chip Packaging, and High Density Interconnection PCB

Symposium Focus: This symposium focuses on issues pertinent to advances in semiconductor interconnects beyond the 20 nm technology node as well as novel materials and integration methods for 2.5D and 3D interconnects. An emerging technology or device architecture called 2.5D and 3D integration is based on the system performance gains that is achieved by chip stacking and vertically interconnecting distinct device layers. Since electrochemical processes are the ultimate solution to create smaller size and lower cost devices, both practical and fundamental aspects of electrochemical processes are of high demand. Ideally, this symposium will bring researchers together to discuss various aspects of device architecture, novel materials, chemical formulation, packaging approaches and nano-scale fabrication methodologies.

A collaborative team of researchers from Shinshu University in Japan have found a new way to curb some of the potential dangers posed by lithium ion batteries.

The team was led by Susumu Arai, a professor of the department of materials chemistry and head of Division for Application of Carbon Materials at the Institute of Carbon Science and Technology at Shinshu University.

These batteries, typically used in electric vehicles and smart grids, could help society realize a low-carbon future, according the authors. The problem is that while lithium could theoretically conduct electricity at high capacity, lithium also results in what is known as thermal runaway during the charge and discharge cycle.

“Lithium metal is inherently unsuitable for use in rechargeable batteries due to posing certain safety risks,” said Arai. “Repeated lithium deposition/dissolution during charge/discharge can cause serious accidents due to the deposition of lithium dendrites that penetrate the separator and induce internal short-circuiting.”
