Abstract
New types of unstable homoepitaxial growth of vicinal surfaces are studied using ex situ atomic force microscopy. The growth features are two types of step bunching with straight step edges between 700 and 775 °C and one type of simultaneous bunching and meandering at 800 °C. The results of a quantitative size scaling analysis of the straight steps are discussed from the perspective of universality classes in bunching theory.
