In this work, Schrodinger equation was solved in the framework of effective mass approximation for an electron in conduction band of InAs/GaAs quantum dot and InAs/In0.2Ga0.8As/GaAs Quantum Dot-in-a-Well structure (DWELL). Eigen-energies, envelop functions, transition lifetime and linear absorption were calculated and compared for both structures. A shift in transition lifetime as well as linear absorption was noticed between the structures and in accordance with experimental results.
Keywords: Linear Absorption, Transition Lifetime, Intersubband Transition, Quantum Dot, Quantum Dot-in-a-Well (DWELL).
