This work presents the clear-cut evidence for Dirac fermions in the quasi-1D telluride TaNiTe5 and shows that its transport behaviors are highly anisotropic and the nontrivial band topology is further corroborated by first-principles calculations. Expand
Transport property of multi-band topological material PtBi\documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy}
Electrical transport of both longitudinal and transverse directions carries rich information. Mobility spectrum analysis (MSA) is capable of extracting charge information from conductivity tensor,Expand
Transport property of multi-band topological material PtBi[Formula: see text] studied by maximum entropy mobility spectrum analysis (MEMSA).
The present results prove MEMSA is a useful tool of extracting carries' information in recently discovered Iron-based superconductors, and topological materials. Expand
