Abstract
Negative resistance and oscillations were observed in germanium diodes, operating in forward direction. Conductance and noise measurements were done in the post‐negative resistance region, where the current voltage characteristic obeys the cube law for a plasma injected into an insulator. The conductance g shows a transit time effect, and the h.f. noise can be represented by a noise current generator (4kTgΔf)1/2 in parallel to the device.Keywords
