| Research Abstract |
It is important to quantify interfaces at the atomistic and electronic levelfor the design of the structure and functions of heterointerfaces in oxide semiconductors and insulators, and compound semiconductors for photovoltaic applications. In this research project, we have developed a computational procedure based on the combination of first-principles calculations at various levels of accuracy and applied it to the heterointerfaces. Data sets relevant to the interfacial structure and functions were constructed in conjunction with experiments and macroscopic simulationsto derive principles for the control and design of the interfaces. Systems that can show high performances as oxide-semiconductor and photovoltaic-semiconductor interfaces were explored.
