Abstract

Structure and "Ferromagnetism" of ZnO

Zinc oxide, ZnO, is a wide band gas semiconductor with a range of technological applications including electronic and electro-optic device, catalysts, chemical sensors, piezoelectric transducers, and conductive solar cell window layers. ZnO has the wurtzite hexagonal structure at ambient condition. Bates et al first discovered a high pressure phase with the rocksalt or NaCl cubic structure. The quenchability of the high pressure phase is a very important problem in the field of materials science. In this talk, we will address 1. How can we quench the high-pressure cubic ZnO phase to ambient condition? 2. How stable is the cubic ZnO phase? 3. What kind of properties does the cubic ZnO phase have? 4. How does the cubic-ZnO phase transfer into hexagonal ZnO phase? 5. is there ferromagnetism of Co-doped ZnO phase?
