摘要：
The binding energy of excitons in quantum well wires of GaAs surrounded by Ga1-xAlxAs was calculated in an effective mass approximation with the use of the variational approach. Results obtained show that the exciton binding energies depend on the sizes of the wire and the strength of the magnetic field. The exciton theory was then used to calculate the linear absorption coefficient of HH1-C1 excitons by varying the wire dimensions and magnetic field values.
