Perovskites are a class of materials with a unique crystal structure that suits applications such as fabricating solar cells, ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward” but ...

A RIKEN study shows that squeezing the right amount of potassium ions between the atomic layers of molybdenum disulfide can turn it from a semiconductor into a metal, superconductor or insulator. The ...

Electronic skins need to be exceptionally thin to practically work as they need to be unnoticeable by the naked eye. Thankfully, a group of scientists has devised a way to achieve just that with ...
