Subject : Oxides in Electronics

Speaker: Chris G. Van de Walle, Materials Department, University of California, Santa Barbara

Abstract:

Oxides have many applications, ranging from gas sensors to varistors.  They are increasingly being used in electronics and optoelectronics.  Transparent conducting oxides (TCOs) such as ZnO, SnO₂, and In₂O₃, provide metallic conductivity while absorbing little or no visible light; they are essential for devices such as solar cells, light-emitting diodes, and flat-panel displays.  TiO₂ has applications in solar cells and (photo)catalysis, and also, along with Al₂O₃, Ga₂O₃, SiO₂ and MgO, as a dielectric. Controllable p-type doping would in principle allow for optoelectronic devices such as light emitting diodes and detectors. … (click here for full abstract)
