Magneto-intersuband resistance oscillations in a one-dimensional lateral superlattice

This paper presents the results of a study of magneto-intersubband resistance oscillations in a one-dimensional lateral superlattice fabricated on the basis of a single GaAs quantum well with two filled energy subbands. A strong  modification of magneto-intersubband oscillations both in amplitude and in phase has been observed. The obtained experimental data are explained by the role of Van Hove singularities in resonant intersubband transitions.
