The Energy Spectrum of Field Emission Electrons from 4H Silicon Carbide

Measurements of field emission energy distribution (FEED) by the retarding potential method have been performed for electron emission from the top of mono crystal macroemitter, made by the sublimation method, N doped (n-type) on 4 deg. off 4H-SiC wafers (0001-C). A peculiar feature, revealed from the FEED patterns is the existence of two maxima.
