Mark S. Golden,Emmanouil Frantzeskakis,Nick de Jong,Yingkai Huang,D. Wu,Yu Pan,Anne de Visser,Erik van Heumen,T. V. Bay,B. Zwartsenberg,Pieter Pronk,S. V. Ramankutty,A. Tytarenko,Nan Xu,Nicholas C. Plumb,Ming Shi,Milan Radovic,Andrei Varkhalov +17 more
TL;DR: It is shown, using angle-resolved photoemission, how an EUV light beam of moderate flux can be used to exclude topologically trivial states from the Fermi level of Bi1.7Se1.3 single crystals, thereby re-establishing the purely topological character of the low lying electronic states of the system.
