Anomalous screening in two-dimensional materials with an extremum ring in the dispersion law

21 Dec 2016 Kolomeisky Eugene B. Straley Joseph P.

A variety of two-dimensional materials possess a band structure with an energy extremal ridge along a ring in momentum space. Examples are biased bilayer graphene, and surfaces and interfaces with a Rashba spin-orbit interaction where at low doping the carriers fill an annulus... (read more)
