Equilibrium faceting formation in vicinal Al2O3 (0001) surface caused by annealing
FOX, DANIEL; SHVETS, IGOR; FLEISCHER, KARSTEN; ZHANG, HONGZHOU; USOV, VICTOR; VERRE, RUGGERO; SOFIN, SUMESH; BEHAN, G. (Elsevier B.V., 2012-07)We report on a heat-induced transformation of the surface of ?-alumina (0001) crystals which have an off-cut in the [1-210] direction. Annealing the crystal causes the surface to transform into a regular array of (0001) ... -
