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…

Emergence of metallic surface states and negative differential conductance in thin $β$ -FeSi $_{2}$ films on Si(001)

Keisuke Sagisaka, Tomoko Kusawake, David Bowler +1

The electronic properties of the surface of $β$ -FeSi $_{2}$ have been debated for a long while. We studied the surface states of $β$ -FeSi $_{2}$ films grown on Si(001) substrates using s…

Single-layer Graphene Nearly 100% Covering an Entire Substrate

Mingsheng Xu, Daisuke Fujita, Keisuke Sagisaka +2

Graphene has recently attracted a great deal of interest in both academia and industry because of its unique electronic and optical properties [1,2], as well as its chemical, therm…
