Abstract
To study the momentum relaxation rate, ( 1 τ D ), between barrier coupled 2D and 1D systems as well as its transition behavior from 2D-2D coupled systems to 2D-1D or 1D-1D coupled systems, we investigate a system which is composed of a couple of barrier separated cylindrical quantum wells with a common rotated center. As the first step, we calculated the momentum relaxation rate between 2D and 1D cylindrical quantum wells. We find that 1 (τ D) is a monotonically increasing function of T in the temperature range of 0–30 K and 1 (τ D T 4) exhibits a maximum at T=T max. The value of ( τ D −1 (T max ) 4 ) is proportional to d −3 times a nearly periodic function of d where d is the separation distance between two wells.
