Abstract

The photodetector based on optical rectification effect (ORE) was created using nanostructured carbon (nanographite) films. Sensitivity of the photodetector was studied in dependence on the carbon films size. It is shown that amplitude of electrical pulses generated by the photodetector depends on the thickness, length and width of the film area. The maximal sensitivity is reached at the film thickness of about 2.5 micrometers. It is shown also that the photoelectrical pulses appearing on the nanographite film have different nature than those appearing in on the silicon substrate.
