From: Electronic and chemical structure of the H2O/GaN(0001) interface under ambient conditions

Scheme showing simplified chemical and band structure evolutions at the H2O/GaN(0001) interface.
The band structures of three representative experimental conditions were used, i.e., UHV, 0.1 mbar of H2O at room temperature and 0.1 mbar of H2O at 773 K.
