P. Kleinert et Vv. Bryksin, High-field miniband transport in semiconductor superlattices in a quantizing magnetic field, SUPERLATT M, 25(1-2), 1999, pp. 33-37
Miniband transport in semiconductor superlattices in high electric and magn
etic fields aligned parallel to the symmetry axis is studied within a quant
um-kinetic approach that accounts for intra-collisional field effects of bo
th fields and the heating of the lateral electron motion. Scattering on aco
ustical and optical phonons as well as impurities is taken into account. Do
minating elastic scattering under the condition of strong lifetime broadeni
ng and weak screening leads to monotonous current-voltage characteristics.
Stark-cyclotronphonon resonances are strongly enhanced by a magnetic field
and are predicted to occur in systems, where the elastic scattering is weak
compared with scattering on polar-optical phonons. (C) 1999 Academic Press
