High mobility graphene Researchers at the Georgia Institute of Technology and Tianjin University created a functional semiconductor made from graphene that is compatible with conventional microelectronics processing methods. "We now have an extremely robust graphene semiconductor with 10 times the mobility of silicon, and which also has unique properties not available in silicon," said Walt... » read more

Chip Industry’s Technical Paper Roundup: Apr. 18
By Linda Christensen - 18 Apr, 2023 - Comments: 0

New technical papers recently added to Semiconductor Engineering’s library: [table id=93 /]   If you have research papers you are trying to promote, we will review them to see if they are a good fit for our global audience. At a minimum, papers need to be well researched and documented, relevant to the semiconductor ecosystem, and free of marketing bias. There is no cost involv... » read more

Frozen finFETs The Defense Advanced Research Projects Agency (DARPA) has launched the Low Temperature Logic Technology (LTLT) program, an effort to develop finFETs that operate at temperatures close to liquid nitrogen (~77K or minus 321 degrees Fahrenheit). The goal of LTLT is to develop low-temperature finFET transistors at the 14nm node and below by making modifications to the manufacturi... » read more

Power beams The U.S. Naval Research Laboratory and PowerLight Technologies have demonstrated the ability to transmit energy using a long-range, free-space power beaming system. The system is being developed as part of the Power Transmitted Over Laser (PTROL) project. The system consists of two 13-foot-high towers. One tower consists of 2-kilowatt laser transmitter. The other tower consist o... » read more

More speculative vulnerabilities Security researchers at the Graz University of Technology, KU Leuven, Cyberus Technology, and Worcester Polytechnic Institute point to two new speculative execution vulnerabilities related to Meltdown and Spectre. The first, which they dubbed ZombieLoad, uses a similar approach to Meltdown. After preparing tasks in parallel, the processor needs to discard th... » read more

Polymer pen litho Using a polymer pen lithography technique, the Air Force Research Laboratory and Northwestern University have developed a quick way to discover new materials. Researchers have developed a combinatorial library of tiny nanoparticles on a substrate. A combinatorial library, sometimes referred to as a megalibrary, is a collection of different structures. Each structure is enc... » read more

For the past half-century, chipmakers have been following the same roadmap for improving performance in chips and reducing the cost of chips. That has proven tremendously effective in reducing costs and packing computing into a smaller space, allowing people to carry around what used to be a multi-million-dollar mainframe in their pocket. That approach is beginning to lose momentum. It's ge... » read more

Adaptive materials The U.S. Army Research Laboratory (ARL) and the University of Maryland have developed a technique to make adaptive materials. Using ultraviolet light, researchers have devised a way that causes a composite material to become stiffer and stronger on-demand. This in turn could enable a variety of new capabilities for the U.S. military, such as rotorcraft design. In this... » read more
