Topological delocalization against Anderson localization observed in Bi-doped PbSb2Te4 disordered topological insulator
Yuya Hattori, Koichiro Yaji, Keisuke Sagisaka +6
We experimentally investigate the tendency of localization in the bulk and the topological surface states in topological insulators Pb(Bi1-xSbx)2Te4 (x=0.793-0.818) through detaile…
