Abstract :
Small-signal negative conductances from 5 to 17 GHz in both voltage polarities are reported for CW-operated 10-µm supercritically doped n+nn+GaAs transferred electron devices. The conceptually different behavior in the two polarities for the frequency dependence of the negative conductance is interpreated by means of computer simulations, and the stabilizing mechanisms involved are discussed.
