In this paper, the fabrication and characterisation of pentacene-based photoconductors using indium tin oxide electrodes obtained by ion beam sputtering are discussed. The photoelectric properties of pentacene under red (632 nm) and ultraviolet (365 nm) illuminations were investigated. We have shown that the photocurrent was dependent on the wavelength, bias voltage and illumination side of the...

In the persistent photoconductivity (PPC) phenomena, illumination of a material with light leads to a long-lived photoconductive state. During illumination of oxygen deficient YBCO near the insulator–metal transition, the illuminated material may even become superconducting. Accompanying the large relative changes in resistance are transport and structural changes as well as changes in the phot...

We investigate the effect of molecular oxygen on photoconductivity monolayer MoS2 via broad-band time-resolved terahertz spectroscopy. observe that MoS2...

One of the ways to solve multiple problems optical diagnostics is use photovoltaic converters based on semiconductors with intrinsic photoconductivity slightly doped deep impurities which form several energy levels different charge states within semiconductor′s bandgap. Peculiarities physical processes recharging these make it possible construct photodetectors functionality a range simple devic...

the absorption properties of charge transfer organic semiconductor ttf-tcnq (tetrathiafulvalene-tetracyanoquhodimete ) filmsdeposited on kbr singlecrystal, quartz and glass substrates in far infrared have been investigated. an absorption edge at ?10 ??m was observed. photoconductivity, photoconduction efficiency and gain and photocarrier's lifetime have been measured. the results show an e...
