zinc oxide (ZnO)

Zinc oxide (ZnO) has so far not been very suitable as a semiconductor material because p-doping causes problems and zinc oxide is difficult to dope with foreign atoms. It is used in electronics and photovoltaics, for example in photoresistors and as transparent conductive oxides (TCO) in solar cells, but in these and similar applications as a conductor or light-dependent material.

Recent research results show that the problems with p-doping can be solved and zinc oxide could thus replace some semiconductor materials. Blue light-emitting diodes (LEDs), which have so far been made of gallium nitride (GaN), or as transparent contact fingers of thin-film solar cells are being considered.
