79‐4: Theoretical Prediction of Changes in Emission and Absorption Spectra of InP‐ and InGaP‐based Quantum Dots and Comparison with Experimental Measurement of InP‐based Quantum Dots

Theoretically calculated emission and absorption spectra of InP/ZnS and InP/ZnSe/ZnS quantum dots (QDs) with the solution of Schrödinger’s equation on the basis of the strain‐modified effective mass approximation (EMA) have been well matched with the experimental measurements. We also predict the em...

Description
Summary:Theoretically calculated emission and absorption spectra of InP/ZnS and InP/ZnSe/ZnS quantum dots (QDs) with the solution of Schrödinger’s equation on the basis of the strain‐modified effective mass approximation (EMA) have been well matched with the experimental measurements. We also predict the emission and absorption spectra of InGaP‐based quantum dots. The intensity of the emission peak wavelength of In0.43Ga0.57P/ZnSe/ZnS has increased more than 60% compared with that of InP/ZnSe/ZnS.
