题目:ZnO: From Optoelectronic Materials to Devices
摘要:
Zinc oxide has attracted much attention in recent year for its wide bandgapand large exciton binding energy, it is expected that efficient excitonic emission and low-threshold lasing may be realized from this kind of materials due to its unique properties. Experimentally, various ZnOluminescences and lasings under optical pumping excitation conditions have been observed. However, to fabricate efficient optoelectronic devices, it is usually necessary to construct p-n junctions.However, ZnO is intrinsically an n-type semiconductor, and p-type doping is a necessity to construct p-n junctions. Such issue has been one of the most challenging issues for ZnO. In this talk, we will show our exploration, thinking, and solutions in this issue.
