Abstract
A very smooth (111) titanium-rich surface was obtained by annealing Sr TiO3 single crystals in UHV. The surface structure was investigated wi th SEM, STM and LEED and was found to consist of terraces, interrupted by multi-unit-cell high steps, obviously a result of step bunching. T he surface unit cell, is enlarged as a result of our particular prepar ation procedure.
