Effects of nonparabolic bands in quantum wires

A nonparabolic band model has been implemented for a one-dimensional electron gas, using a modified Schrödinger equation which takes into account size quantization in the transverse cross section of a silicon quantum wire. The quantized states and the corresponding one-dimensional density of states have been analyzed when the nonparabolicity is present, to quantify the importance of the effect of realistic bands at higher energies.
