Stark Shift and Permanent Dipole Moment of Vertically Confined Excitons in InAs/GaAs Ring-Like Quantum Dots

The purpose of this work is to present a theoretical study on Stark effect and permanent dipole moment of vertically confined excitons in ring-like quantum dots of InAs embedded in GaAs.

Description
Summary:The purpose of this work is to present a theoretical study on Stark effect and permanent dipole moment of vertically confined excitons in ring-like quantum dots of InAs embedded in GaAs. Similarly to what is observed in dots, this system presents blue shift energy when an electric field is applied from the base to the top of the disk.
