Abstract
Elektrik alan
öngerilimi altındaki testere dişi çift bariyer yapısında rezonans tünelleme
özelliği, sonlu farklar metodu bazlı denge-dışı Green fonksiyonu yöntemiyle
incelenmiştir. Elektrik alan altında testere dişi çift bariyer yapılarının
tünelleme iletim olasılığı ve rezonans enerji durumları sunulmuştur. Nümerik
sonuçlar, iletim katsayısındaki rezonans pikinin, öngerilim alanına ve yapı
parametrelerine kuvvetli bir şekilde bağlı olduğunu göstermektedir.

Abstract
Resonant tunneling properties of
sawtooth double barrier structures under the electric field bias are investigated
in this paper using the non-equilibrium Green’s functions method based on
finite difference method. Tunneling transmission probability and resonant
energy states of sawtooth double barrier structures under the electric field
are presented. Numerical results reveal that the resonant peak in the
transmission coefficient depends strongly on the bias field and structure
parameters.
