Power/Performance Bits: June 28


Making uniform wafers Scientists from the Korea Institute of Machinery & Materials (KIMM) and Nanyang Technological University Singapore (NTU Singapore) propose a technique that combines nanotransfer printing with metal-assisted chemical etching to improve wafer uniformity and increase yield. The researchers used a chemical-free nanotransfer printing technique that transfers gold nanost... » read more

GaN ICs Wanted for Power, EV Markets


Circuits built with discrete GaN components may get the job done, but fully integrated GaN circuits remain the ultimate goal because they would offer many of the same advantages as integrated silicon circuits. These benefits include lower cost as the circuit footprint is scaled, and reduced parasitic resistance and capacitance with shorter interconnect runs. In addition, improved device perf... » 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

Power/Performance Bits: June 4


Flexible high-temp dielectric Researchers at Rice University, Georgia Institute of Technology, and Cornell University developed a new high-temperature dielectric nanocomposite for flexible electronics, energy storage, and electric devices that combines one-dimensional polymer nanofibers and two-dimensional boron nitride nanosheets. The polymer nanofibers act as a structural reinforcement, w... » read more

MicroLEDs: The Next Revolution In Displays?


Flat-panel display technology is exploding on several fronts as more screens are required for more devices. But one type of display is generating an enormous amount of buzz in the market—microLEDs. Dozens of companies are working on micro-light emitting diodes (microLEDs), a technology that promises to provide better and brighter displays than current solutions in the market. Apple, Facebo... » read more

Power/Performance Bits: April 17


Flexible LCDs Researchers at Donghua University and Hong Kong University of Science and Technology developed a flexible, optically rewriteable LCD for paperlike displays. The team estimates it will be cheap to produce, perhaps only costing $5 for a 5-inch screen. Optically rewriteable LCDs, like conventional LCDs, are structured like a sandwich, with a liquid crystal filling between two ... » read more

Tiny lasers on silicon A group of scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories, and Harvard University were able to fabricate tiny lasers directly on silicon. To do this, they first had to resolve silicon crystal lattice defects to a point where the cavities were essentially equivalent to those gr... » read more
