We have investigated the THz response of a series of GaAs/Al x Ga 1- x As superlattices with a variety of miniband widths. The samples range from the sequential resonant tunneling limit with a very narrow miniband to superlattices with a miniband wid

Quantum transport in resonant tunneling diodes, sequential resonant tunneling superlattices and miniband superlattices in the presence of intense terahertz electric fields is marked by new channels opened by the absorption or emission of one or more

Perturbation theory is used to understand the transitions that dominate photon-assisted tunneling in coupled quantum-well systems immersed in intense ac fields. In particular, we show that the Bessel functions, widely incorporated into models describ
