Charge puddles in the bulk and on the surface of the topological insulator BiSbTeSe studied by scanning tunneling microscopy and optical spectroscopy
T. Knispel, W. Jolie, N. Borgwardt +6
The topological insulator BiSbTeSe corresponds to a compensated semiconductor in which strong Coulomb disorder gives rise to the formation of charge puddles, i.e., local accumu…

Revealing puddles of electrons and holes in compensated topological insulators
N. Borgwardt, J. Lux, I. Vergara +7
Three-dimensional topological insulators harbour metallic surface states with exotic properties. In transport or optics, these properties are typically masked by defect-induced bul…
