论文摘要
我们的研究重点是通过磷载体超级晶格的电荷载体的传输差距，该载体由一系列障碍物和井组成，产生了$ n $相同的细胞。我们使用Bloch的定理和转移矩阵方法确定能量谱的解，然后确定传输。该分析将对入射能，屏障高度，潜在宽度，周期数和横向波向量对传输的影响进行。我们表明，伪隙会出现，并通过增加细胞数量而变成实际传输差距。它们的数量，宽度和位置可以通过更改结构的物理参数来调节。在正常发生率下，发现了一个禁止的间隙，这意味着与石墨烯相比，没有klein隧道效应。我们的发现可用于创建各种基于磷的电子设备。
Our research focuses on the transmission gaps of charge carriers passing through phosphorene superlattice, which are made up of a series of barriers and wells generating $n$ identical cells. We determine the solutions of the energy spectrum and then transmission using Bloch's theorem and the transfer-matrix approach. The analysis will be done on the impact of incident energy, barrier height, potential widths, period number, and transverse wave vector on transmission. We show that pseudo-gaps appear and turn into real transmission gaps by increasing the number of cells. Their number, width, and position can be tuned by changing the physical parameters of the structure. At normal incidence, a forbidden gap is found, meaning that there is no Klein tunneling effect, in contrast to the case of graphene. Our findings can be used to create a variety of phosphorene-based electronic devices.
