Electronic properties of rolled-up materials — •Carmine Ortix and Jeroen van den Brink — Leibniz-Institute for Solid State and Materials Research Dresden, D-01171 Dresden, Germany

The success achieved in modern nanotechnology has made it possible to develop systems having fairly complex geometrical shapes. Typical examples are the so-called rolled-up nanotubes which mimic the cylindrical geometry of a radial crystal. In this talk we will discuss the electronic properties of a rolled-up two-dimensional electron gas. The nature and energy dispersion of the quantum states reflect the interplay between the typical length scales of the problem. In addition we will show that the effect of an external magnetic field adds a new degree of freedom to manipulate the quantum states of the carriers.
