论文摘要
我们在2D和3D半学中通过矩形电势屏障进行了矩形电势屏障的隧穿,其带状结构由二次带交叉点组成。我们以各种入射角度计算传输系数,还证明了电导率和FANO因子的行为。我们讨论了与其他半法和正常金属中的电子相比,这些传输特性的区别特征。
We investigate the tunneling of quasiparticles through a rectangular potential barrier of finite height and width, in 2d and 3d semimetals with band structures consisting of a quadratic band crossing point. We compute the transmission coefficient at various incident angles, and also demonstrate the behaviour of the conductivity and the Fano factor. We discuss the distinguishing signatures of these transport properties in comparison with other semimetals, as well as electrons in normal metals.
