Analysis of Tunneling Phenomenon and Electron Confinement in Quantum Nanowire

Abstract:

Using Transfer Matrix Method (TMM) the Eigen energy of the GaN/AlGaN quantum wire has been evaluated. Peak density results show the confinement and tunneling of electron distribution in quantum wire due to band offset of GaN (wire region) and AlGaN (barrier region). The impact of this band offset results in variation in Eigen energy and is significant in Tunneling phenomenon study to realize the transmission coefficient across the cross-section. Our analysis reveals that for wider wires transmission coefficient reaches to its peak for lower Eigen energy values. Likewise, increase in aluminum mole fraction in AlGaN decreases tunneling effect.
