Abstract :
It is shown theoretically that the recently observed negative conductance of an interdigital-electrode structure situated near a semiconductor surface is enhanced considerably if a configuration is chosen which is symmetrical with respect to a plane perpendicular to the carrier drift velocity. Furthermore, the threshold drift velocity may be much lower than in the original configuration.
