Boundary Conditions and Surface States Spectra in Topological Insulators

V. V. Enaldiev, I. V. Zagorodnev, V. A. Volkov

We study spectra of surface states in 2D topological insulators (TIs) based on HgTe/(Hg,Cd)Te quantum wells and 3D Bi${}_2$Se${}_3$-type compounds by constructing a class of feasible t…
