Analytical modeling for nanostructure quantum wells with equispaced energy levels in semiconductor ternary alloys (Ax B1-x C)

“…As stated above, the calculated electron effective masses can be used as inputs for further single band calculations to obtain the electronic structure when the absolute size of the structures is known ( [23,25] . The generalized formulation here can be extended to other semiconductors nanostructures such as theoretical design of equispaced energy level quantum wires which are two-dimensional confinement [26] and quantum dots which are three-dimensional confinement [13]. It is expected that the equispaced energy level will reduce the effect of decoherence in these semiconductors nanostructures especially in their applications that require coherent emission and absorption.…”

“…The nano-structuring of semiconductor materials was first introduced by Shockley [9] and later by Kroemer [10], however the progress of nanofabrication technology was affected by decoherence [9][10][11][12]. This has instigated the search for designs which may reduced the decoherence which cannot in principle be eliminated for the obvious reasons of the size of the nanostructure and that there is no physically isolated quantum system in nature [6,13]. One possible way to reduced the effect of decoherence may be to design semiconductors nanostructure with equispaced energy levels which will lead to coherent emission and absorption.…”
