Photoemission studies of topological crystalline insulator Pb$_{1-x}$Sn$_{x}$Se

ORAL

Abstract

Topological crystalline insulators is a class of narrow-gap semiconductors with spin-orbit induced gap inversion and surface states whose topological protection arises from the crystal symmetry. We present a photoemission study of the electronic structure of a rock-salt alloy $Pb_{1-x}Sn_{x}Se$ that forms for $0
