Abstract :
This paper presents electronic structure of InAs/GaAs quantum dots in (111) direction. The cubic and truncated pyramidal shaped quantum dots are adopted. The electronic energy levels are calculated by solving a three-dimensional effective mass Shrödinger equation including a strain modified confinement potential and piezoelectric effects.
