Abstract
The optical properties of a nonsquare quantum well with a hyperbolic potential profile have been analyzed. The quantized energy levels for the confined carriers are determined analytically using the effective mass approximation. The absorption coefficients for an undoped AlGaAs/GaAs hyperbolic quantum‐well structure have been calculated based on the one electron density matrix formulation, taking into account broadening effect due to intraband relaxation by carrier–carrier scattering. The results show that the absorption edge as well as its peak value are more sensitive to well shape than well width.This publication has 15 references indexed in Scilit:
