Microscopic Investigation of semiconductor water interaction on crystal surface
(Ting-Chieh Hung)

Zinc oxide (ZnO) is a large bandgap semiconductor which is widely used as a catalyst, e.g. for the water gas shift reaction. Therefore, it is fundamentally important to understand the interaction of water with ZnO. We investigate the structure and interaction of the ZnO on Ag(111) and water adsorbed onto this supported ZnO layer with multiple surface probe techniques such as scanning tunneling microscopy (STM), low energy electron diffraction (LEED), and photoemission spectroscopy (PES).
