What Is A P-Type Semiconductor? A p-type semiconductor is a type of semiconductor material that shows increased conductivity when donor impurities are introduced. These donor atoms are typically ...

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 ...

(Nanowerk News) Professor Soon-Yong Kwon in the Department of Materials Science and Engineering and the Graduate School of Semiconductor Materials and Devices Engineering at UNIST, in collaboration ...

ZnSc 2 S 4 exhibits a direct bandgap and can emit light from orange to blue. Its composition can be chemically tuned to switch between n-type and p-type conduction over nine orders of magnitude, ...

Scientists demonstrate double charge carrier type switching of tin SnSe semiconductor by doping of antimony Sb. The SnSe carrier type switches from p-type to n-type, and re-switches to p-type as ...

P-type dye-sensitised solar cells (p-DSSCs) represent a promising class of photovoltaic devices that utilise p-type semiconductors – most commonly nickel oxide – as the photoactive electrode. These ...

A semiconductor is a material or device that only conducts electricity under certain conditions. Some elements in the periodic table, such as carbon, silicon, and germanium, are intrinsic ...

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 ...
