RHEED Study of Surface Reconstruction at Clean Ge(110) Surface

Abstract
Surface reconstruction at a clean Ge(110) surface is reported to show uncommon features such as the reappearance of the low-temperature phase at higher temperature and temperature-dependent faceting. In order to investigate the features in detail, in-situ RHEED observations of cleaned and annealed Ge(110) surfaces were undertaken. The reap-pearance phenomenon was confirmed in the present RHEED observation, but no faceting occurred.
