(a) Photocurrent induced by white light illumination of as a function of the bias voltage of samples A and B. is the correlation coefficient of the best fit. (b) Photocurrent as a function of white light power density at a bias voltage for samples A and B.

Image of FIG. 3.
FIG. 3.

(a) Normalized photoconductance spectra of samples A and B, obtained by illuminating the whole surface samples with filtered light (◼ and ○ symbols) as well as a small part of the surface samples with laser spots (black and white star symbols). The solid and dashed lines indicate the absorbance spectra of samples A and B, respectively. (b) The EELS of samples A and B are shown. For comparison the EELS spectrum of the highly ordered pyrolitic graphite is also reported.
