Drawing of a plasma BJT in which the collector plasma is confined within a cavity fabricated in dielectric (shown in blue), a portion of which has been cut away for clarity. The cavity also serves to expose the collector plasma to the base.
Generalized diagram of a plasma BJT operating in the normal mode in which the emitter-base junction is forward biased. All red and blue arrows indicate the direction of local electron and hole flow, respectively. The green arrow represents plasma-produced photons incident on the base.
Cross-sectional diagram (not to scale) of one configuration of an PBJT that has been fabricated and tested to date.
Collector current -base current characteristics for a PBJT having a collector diameter of 3 mm and a Ne gas pressure of 25 Torr. The base-emitter junction is driven by a 200 Hz sinusoidal voltage waveform with an rms value of 2.8 V. Throughout these measurements, the collector anode was planar.
