Abstract: This letter reports a novel photodetector based on a metal-oxide-semiconductor field-effect transistor with a grating-gate structure, which was fabricated by employing the standard 0.8-µm complementary metal-oxide-semiconductor process. The use of a periodical slit structure allows… read more here.
