The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities. Doping with isovalent and larger-sized alkali ...

French scientists have studied the fabrication of silicon heterojunction cells with p-type wafers. With the adoption of gallium doping, the p-type products could come close to matching the performance ...

Doping in semiconductors is adding a small amount of impurities into a very pure semiconductor material. It might sound strange to add impurities on purpose, but this is a critical to make ...

Many modern electronic devices we use daily owe their existence to the process of semiconductor doping. Doped semiconductors are the result of careful modifications ...

Major processes in semiconductor wafer fabrication: 1) wafer preparation, 2) pattern transfer, 3) doping, 4) deposition, 5) etching, and 6) packaging. The process of creating semiconductors can be ...

(Nanowerk News) The carrier concentration and conductivity in p-type monovalent copper semiconductors can be significantly enhanced by adding alkali metal impurities, as shown recently by Tokyo Tech ...

Perovskite solar cells have been the subject of much research as the next generation of photovoltaic devices. However, many challenges remain to be overcome for the practical application. One of them ...
