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 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

具有二次带交叉点的费米系统中的隧道

我们研究准粒子通过有限高度和宽度的矩形势垒的隧穿，在具有由二次带交叉点组成的带结构的 2d 和 3d 半金属中。我们计算不同入射角的透射系数，以及电导率和 Fano 因子。与其他半金属以及普通金属中的电子相比，我们讨论了这些传输特性的区别特征
