Research Bits: May 16


Germanium-tin transistor Scientists at Forschungszentrum Jülich, CEA-Leti, University of Leeds, Leibniz Institute for High Performance Microelectronics, and RWTH Aachen University fabricated a new type of transistor from a germanium-tin alloy. Charge carriers can move faster in the material than in silicon or germanium, which enables lower voltages in operation. “The germanium–tin syst... » read more

Comprehensive Model of Electron Conduction in Oxide-Based Memristive Devices


Abstract "Memristive devices are two-terminal devices that can change their resistance state upon application of appropriate voltage stimuli. The resistance can be tuned over a wide resistance range enabling applications such as multibit data storage or analog computing-in-memory concepts. One of the most promising classes of memristive devices is based on the valence change mechanism in oxide... » read more

Tools & design EDA industry revenue increased 7.1% year-over-year from $2.95 billion to $3.46 billion in Q3 2021, according to the ESD Alliance. "Geographically, all regions reported double-digit growth, with product categories CAE, Printed Circuit Board and Multi-Chip Module, SIP, and Services also showing double-digit growth," said Walden C. Rhines, Executive Sponsor of the SEMI Electron... » read more

Power/Performance Bits: Nov. 2


GaN CMOS ICs Researchers from the Hong Kong University of Science and Technology (HKUST) are working to increase the functionality available to wide bandgap gallium nitride (GaN) electronics. GaN is frequently used in power electronics, such as power converters and supplies. However, GaN CMOS technology has been hampered by the difficulties in implementing p-channel transistors and integrat... » read more
