Title: Quantum Size Effects In One-dimensional Disordered Quantum Wells
Author: Rey-Gonzalez R.
Schulz P.A.
Abstract: The existence of quantum confinement in one-dimensional disordered quantum wells is verified by means of resonant tunneling signatures in the transmission probability of an electron through a barrier-well-barrier structure. Bona fide confined states in the energy range where the bulk material presents states with a localization length that exceeds at least three times the quantum well width are found. These bona fide quantum well states show clear symmetry properties for the envelope probability density in spite of disorder. The formation of minibands are verified for correlated and uncorrelated disordered superlattices.
