Synopsis

The realization of layered and ring shape nano structures, in which radial motion of charge carriers is limited both on inner and on outer borders, has brought a new class of theoretical problems about the physical processes in such systems . The important feature of theoretical description of layered and ring shape structures is the opportunity of realization of limiting transitions to quantum wells, wires and also to quantum dotes of various geometry. Really, if we fix the thickness of cylindrical nano-layer and increase internal and external radii the system becomes similar to quantum well. On the other hand, if we set the height of cylindrical quantum layer to infinity, and vanishes the internal radius we will get a quantum wire with circular cross section. If we fix the height and vanishes only internal radius we will get a cylindrical quantum dot. Thus, the results received for layered and ring shape systems have general character and for this reason cause essential interest.
