Structure of Ge(111) Surfaces Obtained by Cleavage in Superhigh Vacuum at Low Temperatures

Early low-temperature LEED results for Ge(111) surfaces obtained by cleavage in vacuum ( approx 10 exp --10 torr) are reported. The atomic structure of Ge(111) surfaces is found to be essentially dependent on cleavage temperature. It has been established that temperature changes over the range 12-30...

Description
Summary:Early low-temperature LEED results for Ge(111) surfaces obtained by cleavage in vacuum ( approx 10 exp --10 torr) are reported. The atomic structure of Ge(111) surfaces is found to be essentially dependent on cleavage temperature. It has been established that temperature changes over the range 12-300K after cleavage have no effect on the surface structure. Upon cleavage at low temperature (T sub c = > 40-60K) cleavage, the Ge(111)-2 x 1 pattern is found. 8 ref.--AA
