Abstract

Deep level transient spectroscopy (DLTS) has been applied to study the carrier emission from states of a 10-layer system of tunnel-coupled vertically correlated quantum dots (VCQDs) in p-n InAs/GaAs heterostructures with different widths of GaAs spacers under varied reverse bias (Ur) and filling voltage pulse Uf.

Abstract

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. [ABSTRACT FROM AUTHOR]

Abstract

Wannier-Stark localization effect for miniband states has been observed in a 10-layer system of tunneling-coupled vertically correlated InAs/GaAs quantum dots (QDs) at different applied electric fields by using deep level transient and differential-absorption spectroscopies. [ABSTRACT FROM AUTHOR]
