Power/Performance Bits: April 11

High-efficiency silicon photodetector Electrical engineers at the University of California, Davis, and W&WSens Devices, Inc. built a new type of high-efficiency photodetector that could be monolithically integrated with silicon electronics. The new detector uses tapered holes in a silicon wafer to divert photons sideways, preserving the speed of thin-layer silicon and the efficiency o... » read more

System Bits: March 3

Observing antiferromagnetic order in ultracold atoms Rice University researchers have simulated superconducting materials and made headway on a problem that’s vexed physicists for nearly three decades using ultracold atoms as a stand-in for electrons. The research team, led by Rice, included researchers from Ohio State University, Universidade Federal do Rio de Janeiro, University of Cal... » read more
