Abstract
The reverse current range of a Knudsen diode with surface ionization is studied under overneutralized conditions in the presence of electron emission from the collector. The difficulty of the problem is associated with the need to consider three particle flows: ions and electrons from the emitter and electrons from the collector. This work consists of two parts. In the first part, the potential distributions and I-V characteristics for plasma regimes, where the potential distribution has a quasi-neutrality portion, are calculated. In the second, the diode with a small electrode spacing, where the near-electrode potential jumps overlap, is investigated. The asymptotic behavior of the current under high negative voltages is examined. Data obtained are compared with the classical Langmuir results for the diode with two opposing electron and ion flows.
