Abstract
The occurrence of high-frequency impatt oscillations is related to the presence of charged deep donor-states as generated by irradiation processes for carrier-lifetime control. This effect is well-known in electron-radiated devices. Device simulation predicts a similar effect in locally lifetime-controlled helium-radiated devices. The experiment gives an approval of the simulation results but shows some unexpected effects too.
