Probing the Electronic Structure at the Boundary of Topological Insulators in the ${\mathrm{Bi}}_2{\mathrm{Se}}_3$ Family by Combined STM and AFM

Christoph S. Setescak, Irene Aguilera, Adrian Weindl +3

We develop a numerical scheme for the calculation of tunneling current $I$ and differential conductance $\mathsf{d}I/\mathsf{d}V$ of metal and CO-terminated STM tips on the topolog…
