A. Wacker et Ap. Jauho, IMPACT OF INTERFACE ROUGHNESS ON PERPENDICULAR TRANSPORT AND DOMAIN FORMATION IN SUPERLATTICES, Superlattices and microstructures, 23(2), 1998, pp. 297-300
A microscopic calculation of the perpendicular current in doped multip
le quantum wells is presented. Interface roughness is shown to affect
the resonant transitions as well as to cause a nonresonant background
current. The theoretical characteristics exhibit several branches due
to the formation of electric field domains in quantitative agreement w
ith experimental data. (C) 1998 Academic Press Limited.
