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.
similar transport properties have been studied in arXiv:2004.14749 and arXiv:2012.15567; there were some typographical errors in the published version -- this arxiv version contains the corrected results; the corrigendum has been published in Annals of Physics 440C, 168825 (2022)
