摘要：
Analytic expressions obtained in the present paper make it easy to calculate the binding energy of an exciton in a quantum well. The binding energy of an exciton and the spectral position of an exciton peak are calculated for stresses In(x) Ga1-x As/GaAs quantum well structures with well widths in the range 5-100 angstrom and with x up to 0.5. The optimal parameters of a quantum well, ensuring the maximum binding energy of an exciton, are determined as a function of the wavelength corresponding to an exciton peak.
