FIG. 1.

Mott-Schottky plot for bulk n-type 4H-SiC (0.5 mol/l Na2SO4 aqueous solution). The intercept with the x-axis corresponds to the flat band potential.

FIG. 3.

Time dependence of photocurrents for the n-type samples under light illumination in the aqueous H2SO4 solution.

Image of FIG. 4.
FIG. 4.

Time dependence of photocurrents for the p-type samples under light illumination in the aqueous H2SO4 solution.
