Volkov-Pankratov states in topological heterojunctions
S. Tchoumakov, V. Jouffrey, A. Inhofer +4
We show that a smooth interface between two insulators of opposite topological Z2 indices possesses multiple surface states, both massless and massive. While the massless surface s…

Observation of Volkov-Pankratov states in topological HgTe heterojunctions using high-frequency compressibility
A. Inhofer, S. Tchoumakov, B. A. Assaf +13
It is well established that topological insulators sustain Dirac fermion surface states as a consequence of band inversion in the bulk. These states have a helical spin polarizatio…
