dc.description.abstract | A comparative study of the morphological surface evolution of c-plane (0001) alpha-Al2O3 upon annealing was investigated for non-miscut (i.e. substrates with 0 degrees nominal miscut) and vicinal substrates. The samples were annealed in air at 1100 degrees C for different durations of time. Although non-miscut samples do not show any step bunching at this temperature, miscut substrates show a regular and ordered stepped morphology with clearly defined terraces as revealed by Atomic Force Microscopy (AFM) and Transmission Electron Microscopy (TEM) image analysis. The surface morphology presents a number of coalescence points, i.e. locations where two steps merge and form a multiple step. Close to the coalescence points, parallel steps change direction to different low index direction. | en |
