Size Dependence of Quantized Energy Levels in Quantum Dash Structures

摘要

Electronic states in a quantum dash structure are calculated using the so called single-band eigenfunction expansion method. This technique allows easy determination of the quantized energy levels and the corresponding wave functions by inverting a Hermitian matrix. Accuracy of this calculation is verified by comparing the results to those obtained from an accurate finite element method. The technique is applied to investigate the dependence of the quantized energy levels on the dimensions of the quantum dash structures.
