Va. Gritsenko et al., THERMALLY ASSISTED HOLE TUNNELING AT THE AU-SI3N4 INTERFACE AND THE ENERGY-BAND DIAGRAM OF METAL-NITRIDE-OXIDE-SEMICONDUCTOR STRUCTURES, Physical review. B, Condensed matter, 57(4), 1998, pp. 2081-2083
Thermally assisted tunneling of holes at the Au-Si3N4 interface was ex
perimentally observed. The hole barrier of 1.6+/-0.2 eV and the effect
ive masses for the hole and electron tunneling into silicon nitride ha
ve been determined. A revised energy-band diagram of the metal-nitride
-oxide-semiconductor structure is constructed.
