Tunneling in Fermi Systems with Quadratic Band Crossing Points
arXiv:2004.06134 · doi:10.1016/j.aop.2020.168235
Abstract
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.
