Electron and Hole Levels in Rectangular Quantum Wires

Within the effective mass approximation and the diagonalization method, the problem of electron and hole levels in rectangular quantum wires (QWRs) is investigated in detail. The mismatch of material mass between the wire and the barrier and anisotropy of the hole mass is considered in our calculation. We study the ground-state energy and the first excited-state energy for the case of a magnetic field applied along the wire. The quantum behaviors are similar to that of other QWRs which were studied before.

Electron in a Quantum Wire in the Presence of Parallel and Perpendicular Magnetic Fields

The electron states of self-assembled rectangular quantum wires (QWRs) are investigated in detail in the presence of a magnetic field. The calculations are done in the single band effective mass approximation. We study the electron states for the magnetic fields applied along and perpendicular to the wire, taking into account the different masses of the various particles inside and outside the QWRs. The electron energy and the influence of the magnetic field are discussed in this paper.
