Researchers design next-generation photodetector

Northwestern University researchers have developed a new approach to quantum device design that has produced the first gain-based long-wavelength infrared (LWIR) photodetector using band structure engineering based on a type-II ...

Bending light to engineer improved optical devices and circuits

Rainbows are formed when light bends—or refracts—as it enters and exits a water droplet. The amount that the light bends depends on the color of the light, resulting in white light being separated into a beautiful spectrum ...

Liquid metals come to the rescue of semiconductors

Moore's law is an empirical suggestion stating that the number of transistors doubles every few years in integrated circuits (ICs). However, Moore's law has started to fail as transistors are now so small that current silicon-based ...

Peel-apart surfaces drive transistors to the ledge

Semiconductor manufacturers are paying more attention to two-dimensional materials, such as transition metal dichalcogenides (TMDs), following the discovery, at KAUST, of an epitaxial growth process of single-crystal TMDs ...
