Direct observation of quantum confinement of massless Dirac fermions in a topological insulator
Mu Chen, Zhen-Guo Fu, Jun-Ping Peng +9
Since the discovery of topological insulators (TIs)1,2, the peculiar nature of their chiral surface states has been experimentally demonstrated both in bulk and in film materials w…

Mass acquisition of Dirac fermions in Cr-doped topological insulator Sb2Te3 films
Yeping Jiang, Zhi Li, Canli Song +7
We introduce time-reversal-symmetry breaking by doping Cr atoms into the topmost quintuple layer or into the bulk of Sb2Te3 thin films. We find that even at a high Cr-doping level…
