Abstract: | Summary We study the subband energies in quantum wells and quantum wires in the presence of a parallel magnetic field in non-parabolic
semiconductors, on the basis of a generalized dispersion relation considering all types of anisotropies of the energy-band
parameters within the framework ofk·p formalism, by formulating the respective electron energy spectra. It is found, by takingn-Cd3As2 as an example, that the subband energies are greater for quantum wires and smaller for quantum wells, respectively. The magnetic
field diminishes the above values and the corresponding well-known results for quantum-confined parabolic semiconductors have
also been obtained from our generalized expressions under certain limiting conditions. |
