Thin films of topological insulators (TI) attract large attention because of expected topological effects from the inter-surface hybridization of Dirac points. However, these effects may be depleted by unexpectedly large energy smearing $\Gamma$ of surface Dirac points by the random potential of abundant Coulomb impurities. We show that in a typical TI film with large dielectric constant $\sim 50$ sandwiched between two low dielectric constant layers, the Rytova-Chaplik-Entin-Keldysh…

This work finds that by reducing the distance from the gate to the film, the spatial range of the 2D long-range logarithmic interaction is decreased, which can be tuned by the external gate electrode and unravel a variety of electrostatic interactions in high-k films.
