Surface sensitive techniques [scanning tunneling microscopy (STM), reflection high-energy electron diffraction (RHEED), and Anger electron spectroscopy (AES) have been used to study the effects of changes in the bulk on the surface structure in TiO 2 . Annealing of TiO 2 (110) at elevated temperatures leads to straight steps on the surface with lengths in excess of 500 a. The structure...
Dynamic events occurring at InP(110) surfaces as a result of thermal annealing have been observed in situ by reflection electron microscopy using a modified ultrahigh-vacuum transmission electron microscope equipped with a specimen heating holder. The motion of screw dislocations across the surface was observed at temperatures in excess of 550 o C, resulting in the formation of new surface...
