Description
Summary:The problem of electron levels in InAs/InP elliptical quantum wires (QWRs) is investigated in detail by using the effective mass approximation and the diagonalization method. In cases of both the absence and presence of a magnetic field the electron states are given as functions of the ellipticity and parameter. The calculations show that the energy levels in elliptical quantum wires are dramatically influenced by the shape of the wires and the energy decreases as the eccentricity increasing when the parameter is fixed, and decreases as the parameter increasing when the ellipticity is fixed. The quantum behaviors of elliptical quantum wires are similar to that of other shaped QWRs which were studied before.
