Spectral function of InAs∕InGaAs quantum dots in a well detector using Green’s function
Abstract
Theoretical modeling of an InAs∕InGaAs quantum dot-in-a well (DWELL) detector is reported. The DWELL structure consists of pyramidal-shaped InAs quantum dots with dimensions of 11nm (base) and 6.5nm (height) placed on the top half of an InGaAs quantum well of 11nm width, which is buried in a GaAs matrix. The Green’s function method is used to calculate the spectral function and the density of states of the DWELL. The kinetic equation that …
