Acceptors in ZnO nanocrystals

While zinc oxide (ZnO) has potential for optoelectronic applications, the lack of reliable p -type doping remains a major challenge. We provide evidence that ZnO nanocrystals contain uncompensated acceptors. IR absorption peaks at liquid-helium temperatures suggest a hydrogenic acceptor with a hole...
