Tunneling of electrons through the barriers in heterostructures devices is investigated by using the unified Transfer Matrix Method. The effect of barrier width on electron transmission coefficients has also been examined for different pairs of semiconductor devices of significant research interest in current years. Such Pairs involve: AlxGa1-xAs/GaAs, AlSb/InAs, and CdS/CdSe quantum barriers with varying dimensions reduced from 20 nm to 5nm to observe how tunneling properties are affected by scaling. The effective electron masses in the well and barrier regions typically vary with constituent materials. It has been shown that the transmission coefficients are significantly changed due to the coupling. The effective mass dependent transmission coefficients for electron energy have been evaluated in terms of the mass discontinuity metrics. The electron transmission coefficients for each pair of quantum structures are plotted with the variation of its electron energy, normalized to its potential energy. The resonant state obtained here will be beneficial for designing detectors, optical filters, photonic-switching devices and other optoelectronic and photonic devices.

Abstract


Tunneling of electrons through the barriers in heterostructures devices is investigated by using the unified Transfer Matrix Method. The effect of barrier width on electron transmission coefficients has also been examined for different pairs of semiconductor devices of significant research interest in current years. Such Pairs involve: AlxGa1-xAs/GaAs, AlSb/InAs, and CdS/CdSe quantum barriers with varying dimensions reduced from 20 nm to 5nm to observe how tunneling properties are affected by scaling. The effective electron masses in the well and barrier regions typically vary with constituent materials. It has been shown that the transmission coefficients are significantly changed due to the coupling. The effective mass dependent transmission coefficients for electron energy have been evaluated in terms of the mass discontinuity metrics. The electron transmission coefficients for each pair of quantum structures are plotted with the variation of its electron energy, normalized to its potential energy. The resonant state obtained here will be beneficial for designing detectors, optical filters, photonic-switching devices and other optoelectronic and photonic devices.
