Abstract

In article number 2400801, Farhad Khoeini and co-workers present an algorithm to obtain the transmission probability of nanostructures directly from the band structure. To evaluate the transmission coefficient, the number of channels is counted. Band2Trans is an algorithm that treats the bands individually. Each band is modeled based on its extremes, and then the transport coefficient is calculated for them individually. Summing them, which is very convenient when they are arranged in a matrix, gives the transport coefficient.

从低维系统的频带结构中提取透射谱的高效算法(Adv. Theory Simul. 12/2024)
在文章2400801中,Farhad Khoeini及其同事提出了一种直接从能带结构获得纳米结构透射概率的算法。为了评估传输系数,需要计算信道数。Band2Trans是一种单独处理频带的算法。每个波段都基于其极值建立模型,然后分别计算它们的输运系数。把它们加起来,当它们排列在一个矩阵中是很方便的,就得到了输运系数。
