FIG. 1.

(Color online) Charging of the ion beam damage and pristine diamond surfaces as a function of the measurement temperature. The incident electron beam energy and current used in these experiments were 1 keV and 0.5 nA, respectively. Open symbols show the charging after heating and cooling back to RT. Upon cooling the sample irradiated with displays no change in the degree of charging (open triangle), whereas for the dose some degree of annealing is evident (open square). The inset shows the data for the dose replotted as log(charging) vs from which an activation energy of about 1.5 eV can be extracted.

(Color online) Dependence of charging on the intensity of 535 (stars), 637 (triangles), and 850 (squares) nm laser illumination for diamond irradiated with at 1 keV. The incident electron energy and current are 1 keV and 0.5 nA, respectively.

(Color online) Charging of the ion beam damaged diamond surfaces as a function of annealing temperature. The incident electron energy and current are 1 keV and 0.5 nA, respectively. The measurements were taken at room temperature after annealing at the specified temperature.

FIG. 4.

(Color online) Dependence of charging as a function of incident electron current. The electron beam was 1 keV and the electron spot size was 100 μm.
