Research Bits: June 27
By Susan Rambo - 27 Jun, 2023 - Comments: 0

Tunable soliton microcomb Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency combs that can fit on a microchip, which will be useful in photonics. Solitons are solitary waves that keep their shape as they move at a constant speed. The team put an... » read more

Week In Review: Design, Low Power
By Jesse Allen - 28 Apr, 2023 - Comments: 0

The National Institute of Standards and Technology (NIST) outlined its plan for a National Semiconductor Technology Center (NSTC) to be created using a share of the $11 billion in funds from the CHIPS Act marked for research and development. While a large portion of the CHIPS Act investment is set to boost U.S. fabs and manufacturing capabilities, the NSTC aims to also support the design side, ... » read more

Source: University Of Surrey: Eva Bestelink Olivier de Sagazan Lea Motte Max Bateson Benedikt Schultes S. Ravi P. Silva Radu A. Researchers at University of Surrey and Université de Rennes developed a new device, called a Multimodal Transistor (MMT), that is immune to parasitic effects. In the MMT, on/off switching is controlled independently from the amount of current passing th... » read more

Power/Performance Bits: Dec. 23

Detecting early damage in power electronics Researchers at Osaka University to detect early damage in power electronics. The team used acoustic emission analysis to monitor in real time the propagation of cracks in a silicon carbide Schottsky diode during power cycling tests. During the power cycling test, the researchers mimicked repeatedly turning the device on and off, to monitor the res... » read more

Power/Performance Bits: Nov. 7

Speeding up MRAM Researchers at UC Berkeley and UC Riverside developed an ultrafast method for electrically controlling magnetism in certain metals, which could lead to increased performance for magnetic RAM. While the nonvolatility of MRAM is a boon, speeding up the writing of a single bit of information to less than 10 nanoseconds has been a challenge. “The development of a non-volatile... » read more

Power/Performance Bits: May 31
By Jesse Allen - 31 May, 2016 - Comments: 0

Solar thermophotovoltaics A team of MIT researchers demonstrated a device based on a method that enables solar cells to break through a theoretically predicted ceiling on how much sunlight they can convert into electricity. Since 1961 it has been known that there is an absolute theoretical limit, called the Shockley-Queisser Limit, to how efficient traditional solar cells can be in their ... » read more
