Abstract :
Shape, size and density of dots of InP on GaInP and GaAs surfaces, formed in-situ by the strain-induced phase transition from a two-dimensional (Frank-Van der Merwe) into a three-dimensional layer+islands (Stranski-Krastanow) morphology, are investigated. The observations support models which include the kinetics of island formation as important ingredients to explain the rather high size homogeneity of the dots
