E. Ishiguro et al., SYNCHROTRON-RADIATION ETCHING OF DIAMOND SURFACES IN THE LOW-PRESSUREATMOSPHERE OF O-2 AND SF6, Journal of electron spectroscopy and related phenomena, 80, 1996, pp. 77-80
We report that etching of diamond has been successfully performed for
the first time with the aid of synchrotron radiation excitation in the
atmosphere of O-2 even at a low temperature of -140 degrees C.
