Abstract
We have measured the current-voltage (I-V) characteristic of semicondu ctor superlattices in the presence of intense terahertz electric field s produced by free-electron lasers. The nonlinear I-V curves exhibit n ew structure that we attribute to photon-mediated sequential resonant tunneling. This tunneling process consists of well to well sequential tunneling into photon sidebands induced by the terahertz electric fiel ds.
