- 論文の詳細を見る
The lattice polarity and relaxation of a ZnO single-crystal (0001) surface were investigated by coaxial impact-collision ion scattering spectroscopy (CAICISS). The angle dependences of Zn intensity were in excellent agreement with a simulation result for a Zn-face bulk structure, with regard to both peak positions and intensity, which is much better than previous works. We use this advantage to determine the degree of surface relaxation quantitatively. It was found that the topmost Zn layer has an inward relaxation of 2% of the $c$-axis lattice constant.
