Temperature dependent empirical pseudopotential theory for self-assembled quantum dots
Temperature dependent empirical pseudopotential theory for self-assembled quantum dots
We develop a temperature dependent empirical pseudopotential theory to study the electronic and optical properties of self-assembled quantum dots (QDs) at finite temperature. The theory takes the effects of both lattice expansion and lattice vibration into account. We apply the theory to the InAs/GaAs QDs. For the unstrained InAs/GaAs heterostructure, …
