- Abstract:
-
Non-contact atomic force microscopy using a needle sensor with a phase shift feedback mechanism has been used to characterise Al2O3(0 0 0 1) surfaces prepared by annealing in 10-4 mbar partial pressures of oxygen. The preparation procedure leads to flat terraces with lengths in excess of 1000 nm and widths of order 40 nm separated by c/6 steps. The unit cell of the (√31 × √31) R ± 9° reconstruction is resolved, with a single rotational domain on each of the terraces. The 18° rotation between ...
