We have investigated the cooling effect of field emission from semiconductors at temperatures up to 900K. It is found that at high temperatures, field emission cooling is meaningful for cathodes of material with low resistivity such as PbTe. For n-type semiconductors with low resistivity, the Nottingham energy exchange in field emission can be comparable to or greater than the Peltier coefficient.
