  • Abstract
    A theoretical analysis of wetting layer effect on electronic structures of InAs/GaAs truncated-pyramid quantum dots is carried out using an eight-band Fourier transform-based k·p method. Wetting layer changes ground-state energy significantly whereas modifies probability density function only a little. The main acting region of wetting layer is just underneath the base of the dot.
