We study the effect of the shape of different potential barriers on the transmitted charged current whose fermionic population is not monoenergetic but is described by means of an energy spectrum. The generalised Kappa Fermi-Dirac distribution function is able to take into account both equilibrium and non-equilibrium populations of particles by changing the kappa index. Moreover, the corresponding current density can be evaluated using such a distribution. Subsequently, this progressive charged density arrives at the potential barrier, which is considered under several shapes, and the corresponding transmission factor is evaluated. This permits a comparison of the effects for different barriers as well as for different energy states of the incoming current.

使用广义费米-狄拉克电流通过势垒的传输

我们研究了不同势垒的形状对传输的带电电流的影响,其费米子布居不是单能的,而是通过能谱描述的。广义 Kappa Fermi-Dirac 分布函数能够通过改变 kappa 指数同时考虑粒子的平衡和非平衡种群。此外,可以使用这样的分布来评估相应的电流密度。随后,这种渐进的带电密度到达势垒,在几种形状下考虑该势垒,并评估相应的传输因子。这允许比较不同势垒以及传入电流的不同能量状态的影响。
