A Unified View of Topological Phase Transition in Band Theory
TPT in crystals with disorders. Atomic configuration of a trigonal lattice with (a) random vacancies at and with (b) thermal disorder at . Energy gap versus for samples with (c) different and with (d) different . Phase diagram of trigonal lattices with (e) random vacancies in the parameter space of and and with (f) thermal disorder in the parameter space of and . The color represents the size of energy gap.
