Title: Polarization dependences of electroluminescence and absorption of vertically correlated InAs/GaAs QDs

The involvement of heavy-hole ground states in optical transitions for light polarized both in the plane perpendicular to the growth axis (x–y) and along the growth direction z of the structure has been observed in vertically correlated quantum dots (VCQDs). The degree of polarization anisotropy depends on the height of VCQDs, which is related to the z component of the wave function of heavy-hole ground states.
