Abstract
In this work we investigate the two dimensional electron gas on surfaces showing Gaussian bumps. Due to confinement on two dimensional curved space, a geometry-induced potential appears. For surfaces showing single bumps, the geometrical potential gives rise to a geometry-induced quantum ring, as showed in a previous work. For surfaces with multiples bumps, the charge carries may be trapped around the center of these surfaces, which could gives rise to a geometry-induced quantum dot. Our results can be realized on bilayer graphene sheets and we hope that it would lead to new technics of building quantum dots.
