M. Park et al., SECONDARY-ELECTRON EMISSION PATTERNING OF DIAMOND WITH HYDROGEN AND OXYGEN PLASMAS, Applied physics letters, 72(20), 1998, pp. 2580-2582
Secondary electron emission patterning of single crystal diamond surfa
ces with hydrogen and oxygen plasma treatments was demonstrated. Hydro
gen plasma treated regions were much brighter than the oxygen terminat
ed regions. Results of atomic force microscopy confirmed that the obse
rved contrast is not topographical. Several other possible negative el
ectron affinity (or low positive electron affinity) materials such as
chemical vapor deposited (CVD) diamond, aluminum nitride, and tetrahed
rally bonded amorphous carbon (t(x)a-C1-x) were also investigated. Fai
nt image contrast (patterning) was also observed from polycrystalline
CVD diamond and polycrystalline aluminum nitride films; however, no co
ntrast at all was obtained from tetrahedrally bonded amorphous carbon
(t(x)a-C1-x) films. (C) 1998 American Institute of Physics.
