Vl. Humphreys et J. Khachan, SPATIAL CORRELATION OF ELECTRON FIELD-EMISSION SITES WITH NON-DIAMONDCARBON CONTENT IN CVD DIAMOND, Electronics Letters, 31(12), 1995, pp. 1018-1019
Field-induced electron emission is obtained from 15mm diameter CVD pol
ycrystalline diamond films deposited on silicon wafers from a microwav
e discharge. These films were grown such that the percentage of non-di
amond carbon is highest at the edge of the film. It was found that the
majority of the emission sites also occured at the edge of the film.
