Theory of the random potential and conductivity at the surface of a topological insulator
Brian Skinner, B. I. Shklovskii
We study the disorder potential induced by random Coulomb impurities at the surface of a topological insulator (TI). We use a simple model in which positive and negative impurities…
Giant capacitance of a plane capacitor with a two-dimensional electron gas in a magnetic field
Brian Skinner, B. I. Shklovskii
If a clean two-dimensional electron gas (2DEG) with small concentration comprises one (or both) electrodes of a plane capacitor, the resulting capacitance can be larger tha…
Why is the bulk resistivity of topological insulators so small?
Brian Skinner, Tianran Chen, B. I. Shklovskii
As-grown topological insulators (TIs) are typically heavily-doped -type crystals. Compensation by acceptors is used to move the Fermi level to the middle of the band gap, but ev…
A simple variational method for calculating energy and quantum capacitance of an electron gas with screened interactions
Brian Skinner, M. M. Fogler
We describe a variational procedure for calculating the energy of an electron gas in which the long-range Coulomb interaction is truncated by the screening effect of a nearby metal…
