Abstract: (7698 Views)
Quantum-dot (QD) structures have the capability of the infrared intraband transitions because of their 3-dimensional confinement. In this paper, a self-assembled pyramidal InAs/GaAs QD is considered and the effects of the quantum dot geometry, such as the dot height and aspect ratio on the intraband transitions are theoretically studied by EHT formalism. The results show that QD size increase leads to considerable reduction of the beam absorption.
