Gallium nitride (GaN) is a promising semiconductor material that outperforms silicon-based devices. However, optimal performance requires high-quality GaN. Photoluminescence (PL) spectroscopy is a non ...

Rio Tinto said on Monday the Government of Canada has conditionally approved a non-repayable ​contribution of up to C$18.95 ...

Lithium-ion batteries are ubiquitous in consumer electronics such as cellphones and in electric vehicles, but the surrounding ...

Cornell researchers have used high-resolution 3D imaging to detect, for the first time, the atomic-scale defects in computer chips that can sabotage their performance. The imaging method, which was ...

Abstract: In semiconductor chip manufacturing, defect detection is a crucial step for ensuring product quality and process stability. However, obtaining defect images in actual production is highly ...

For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient ...

Future devices will continue to probe the frontier of the very small, and at scales where functionality depends on mere atoms, even the tiniest flaw matters. Researchers at Rice University have shown ...

Abstract: Theoretical models and experimental evidence are presented to show how defect photoionization can enhance the degradation rate of high power, edge-emitting semiconductor lasers. The models ...
