Abstract

We investigate three-dimensional resonant tunnelling (RT) through a double potential barrier with a periodic modulation of the quantum well in the plane of the layers. Both elastic and phonon-assisted RT through transverse minibands separated by minigaps are considered. By using the Breit-Wigner-like formula for the transmission probability we find a more abrupt upward portion (front) of the current-voltage characteristics and a broader negative differential resistance region than in `conventional' RT through double barrier heterostructures. Phonon-assisted tunnelling characteristics follow the same trends.
