Abstract
We investigate the tunneling of pseudospin-1 and pseudospin-3/2 quasiparticles through a barrier consisting of both electrostatic and vector potentials, existing uniformly in a finite region along the transmission axis. First, we find the tunneling coefficients, conductivities, and Fano factors in the absence of the vector potential. Then we repeat the calculations by switching on the relevant magnetic fields. The features show clear distinctions, which can be used to identify the type of semimetals, although both of them exhibit linear band-crossing points.
similar transport properties have been studied in arXiv:2004.06134 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 Physics Letters A 433C, 128027 (2022)
