Photoconductive design • Interdigitated structure • Gold electrodes • 25µm pitch • Free standing CVD diamond (~100µm thick) Many regions are pseudo single crystal UV photodetectors QuickTime and a TIFF (Uncompressed) decompressor are needed to see this picture.
• As fabricated device responsive in the visible • Treated device shows true ‘visible blindness’ • Sharp cut off at band edge (225nm) Spectral response Responsivity (arbitary units) 1E+00 1E-01 1E-02 1E-03 1E-04 1E-05 1E-06 1E-07 1E-08 as fabricated after gas treatment 200 400 600 800 Wavelength (nm) QuickTime and a TIFF (Uncompressed) decompressor are needed to see this picture.
