Band inversion mechanism in topological insulators: A guideline for materials design

Alteration of the topological order by band inversion is a key ingredient of a topologically nontrivial material. Using first-principles calculations for HgTe, PtScBi, and B sub(2) Se sub(3), we argue that it is not accurate to ascribe the band inversion to the spin-orbit coupling. Instead, scalar r...
