Proposed Experimental Realization of Anderson Localization in Random and Incommensurate Artificially Layered Systems

Abstract

We propose that random and incommensurate superlattices be fabricated to study the Anderson localization of their plasma oscillations, which can be measured by Raman scattering. Specific configurations are suggested which, by duality considerations, allow control of the wave functions relative to the mobility edge in the incommensurate case. Localization effects should be easily observable with presently achievable superlattice parameters.
