摘要：

We report the first observation of absolute negative conductance and multiphoton stimulated emission in sequential resonant tunneling semiconductor superlattices driven by intense terahertz electric fields. With increasing terahertz field strength the conductance near zero de bias decreases towards zero and then becomes negative. This is accompanied by new steps and plateaus that are attributed to multiphoton-assisted resonant tunneling between ground states of neighboring quantum wells accompanied by the stimulated emission of a photon.
