The effect of space charge on photon-enhanced thermionic emission in the presence of the bidirectional discharge
Xinqiao Lin, Ousi Pan, Zhimin Yang +3
The bidirectional space charge effects in photon-enhanced thermionic emission (PETE) devices are investigated systematically. First, we precisely determine the carrier concentratio…
