WebThe energy band gap of these films was obtained by absorption spectra. The films were found to have a direct type of transition of band gap occurring at 1.75 eV. The dark electrical conductivity and photoconductivity reveals that the films were semiconducting in nature indicating the suitability of these films for photosensor applications. WebApr 28, 2024 · Abstract The terahertz photoconductivity in epitaxial graphene grown on SiC substrates is investigated in a magnetic field. The magnetic-field dependence of the photoresponse signal amplitude is examined at different electron densities, bias currents, and terahertz radiation intensities. The experimental results are explained well by a …

WebMay 28, 2024 · An amorphous (α) indium-gallium-zinc-oxide (IGZO) thin-film-transistor (TFT) was developed as a precise ultraviolet-light (UV-light) sensor, which is extremely sensitive to photoconductivity. A higher absorption of UV-light via a longer UV-light irradiation time and a higher UV-light intensity shifted the threshold voltage (Vth) to a negatively higher voltage … Photoconductivity is an optical and electrical phenomenon in which a material becomes more electrically conductive due to the absorption of electromagnetic radiation such as visible light, ultraviolet light, infrared light, or gamma radiation. When light is absorbed by a material such as a semiconductor, the number of free electrons and holes increases, resulting in increased electrical conductivity. To cause excitation, the light that …
WebFeb 28, 2012 · To experimentally determine the photoconductivity gain, one can directly measure the currents i and i1. Since the quantities V and l are known and mobilities µ n and µ p can be determined from other measurements, equation ( 5) allows the estimation of the lifetime of free charge carriers. 2.
