CHIPS for America…
Topics: Economics, Electrical Engineering, Materials Science, Semiconductor Technology WASHINGTON — The Biden-Harris administration, through the U.S. Department of Commerce’s National Institute of Standards and Technology, today launched the first CHIPS for America funding opportunity for manufacturing incentives to restore U.S. leadership in semiconductor manufacturing, support good-paying jobs across the semiconductor supply chain, and advance U.S.Continue reading “CHIPS for America…”
Chip Act and Wave Surfing…
Massive subsidies to regain the edge of the US semiconductor industry will not likely succeed unless progress is made in winning the global race of idea flow and monetization. Topics: Applied Physics, Chemistry, Computer Science, Electrical Engineering, Semiconductor Technology Intelligent use of subsidies for winning the global idea race is a must for gaining andContinue reading “Chip Act and Wave Surfing…”

Thermo Limits…
Topics: Climate Change, Computer Science, Electrical Engineering, Global Warming, Semiconductor Technology, Thermodynamics In case you had not noticed, computers are hot—literally. A laptop can pump out thigh-baking heat, while data centers consume an estimated 200 terawatt-hours each year—comparable to the energy consumption of some medium-sized countries. The carbon footprint of information and communication technologies asContinue reading “Thermo Limits…”
Strain and Flow…
Topics: Applied Physics, Condensed Matter Physics, Electrical Engineering Using a technique known as strain engineering, researchers in the US and Germany have constructed an “excitonic wire” – a one-dimensional channel through which electron-hole pairs (excitons) can flow in a two-dimensional semiconductor like water through a pipe. The work could aid the development of a newContinue reading “Strain and Flow…”
Stop-Motion Efficiency…
Topics: Applied Physics, Electrical Engineering, Nanotechnology, Semiconductor Technology A new ultrafast imaging technique that captures the motion of atoms in nanoscale electronic devices has revealed the existence of a short-lived electronic state that could make it possible to develop faster and more energy-efficient computers. The imaging technique, which involves switching the devices on and offContinue reading “Stop-Motion Efficiency…”
Gold Anniversary…
Topics: Electrical Engineering, Materials Science, Nanotechnology, Solid-State Physics It’s not exactly a wedding anniversary, but it is significant. Fifty years ago this month, Intel introduced the first commercial microprocessor, the 4004. Microprocessors are tiny, general-purpose chips that use integrated circuits made up of transistors to process data; they are the core of a modern computer.Continue reading “Gold Anniversary…”
Scrofulous Signaling…
Topics: Applied Physics, Electrical Engineering, Materials Science, Optics ABSTRACT We present results of near-field radio-frequency (RF) imaging at micrometer resolution using an ensemble of nitrogen-vacancy (NV) centers in diamond. The spatial resolution of RF imaging is set by the resolution of an optical microscope, which is markedly higher than the existing RF imaging methods. HighContinue reading “Scrofulous Signaling…”
