Charaterisation works were carried out to study the formation mechanism of twin domain CeO2 growth. ZnO(002) epitaxial films have been successfully grown on Si(111) with CeO2 as a buffer layer by pulsed laser deposition. Charaterisation works were carried out to study the interfaces between the ZnO/CeO2. The interface energetics and the Schottky-barrier heights (SBHs) of NiSi2/HfO2 gate stacks are investigated within the framework of first-principles calculations. It was found that the SBHs are interface structure dependent and vary with abrupt interfacial bonds. | URI: | http://scholarbank.nus.edu.sg/handle/10635/38756 |
