Abstract(summary):

Abstract High quality Ge/High-k perovskite oxide interface is essential to facilitate the high performance metal-oxide semiconductor field-effect transistors and monolithically integrated optoelectronics device performance. The atomic structure and electronic properties of perfect and defective Ge/SrZrO 3 are investigated by first-principles calculations. Both SrO- and ZrO 2 -terminated surfaces can be formed for a comparable range of the ZrO 2 chemical potential. We investigated systematically the Ge atomic initial adsorption on the SrZrO 3 (001) substrate. The top sites of the oxygen atoms are favorable for 1/2 (1/3) monolayer Ge adsorption at SrO (ZrO 2 )-termination. The surface phase diagrams are presented by the calculated surface grand potential. The stable structure and effects of the intrinsic point defects are analyzed for the energetically favorable Ge/SrZrO 3 (001) interfaces. Highlights • The atomic structure and electronic properties of Ge on (001) SrZrO 3 . • Both of SrO- and ZrO 2 -terminated surface are stable for a comparable range. • Ge diffusion is possible in the Ge/SrZrO 3 (001) interface. • The largest charge change happens at the interface.
