Thermionic current reversal

• We have analysed the thermionic current over a potential barrier between a hot and a cold metallic wire, in the absence of an externally applied electric field. Because of the quantum nature of the transmission probability and the temperature behaviour of the Fermi distribution function, under proper conditions the thermionic electric current reverses its direction. However, the heat current remains in the same direction although its magnitude is suppressed.
