Phase transitions, Dirac and Weyl semimetal states in Mn1−x Ge x Bi2Te4

Phase transitions, Dirac and Weyl semimetal states in Mn1−x Ge x Bi2Te4

Abstract Using angle-resolved photoemission spectroscopy (ARPES) and density functional theory (DFT), an experimental and theoretical study of changes in the electronic structure (dispersion dependencies) and corresponding modification of the energy band gap at the Dirac point (DP) for topological i...
