Abstract

In this work, we report on the photo-response of CdS nanoparticles prepared by simple solid state reaction method. The X-ray diffraction (XRD) study has confirmed the formation of cubical zinc blende (c) phase. In the photo-response study, voltage dependence of photocurrent and darkcurrent as well as temporal rise and decay of photocurrent of CdS nanoparticles have been investigated. The photo-response of prepared sample has been measured under visible illumination using thick film of powder with out any binder. The photocurrent (I{sub pc}) and darkcurrent (I{sub dc}) follow power law with applied voltage i.e. I α V{sup r}. The rise and decay of photocurrent show negative photoconductivity.

Visible-blind ultraviolet photodiode fabricated by UV oxidation of metallic zinc on p-Si

Journal Article Zhang, Dongyuan; Uchida, Kazuo; Nozaki, Shinji - Journal of Applied Physics

A UV photodiode fabricated by the UV oxidation of a metallic zinc thin film on p-Si has manifested unique photoresponse characteristics. The electron concentration found by the Hall measurement was 3 × 10{sup 16 }cm{sup −3}, and such a low electron concentration resulted in a low visible photoluminescence. UV illumination enhances the oxidation at low temperatures and decreases the concentration of the oxygen vacancies. The I-V characteristic showed a good rectification with a four-order magnitude difference in the forward and reverse currents at 2 V, and its linear and frequency independent C{sup −2}–V characteristic confirmed an abrupt pn junction. The photoresponse showed a visiblemore »« less

Photoresponse mechanisms of a graphene-based quantum-dot monolayer structure

Journal Article Ammar, J.; Chumakov, A; Glukhovskoy, E; ... - Quantum Electronics (Woodbury, N.Y.)

Hybrid structures of graphene sheets based quantum dots (QDs) are produced via Langmuir–Blodgett (LB) technique. Morphology of the structures produced is investigated by atomic force microscopy (AFM) and scanning electron microscopy (SEM). Two types of hybrid structures are prepared from graphene covered by sublayers of CdSe/CdS/ZnS and CdSe/ZnS QDs. Photocurrent properties are studied by current–voltage characteristics (CVCs) in the dark and while exposed to visible light and ultraviolet (UV) light with an excitation wavelength of 365 nm. The rise and decay times of graphene and QDs after UV illumination are estimated. (laser applications and other topics in quantum electronics)

A simple route to synthesize carbon-nanotube/cadmium-sulfide hybrid heterostructures and their optical properties

Journal Article Yongbin, Zhao; Haijing, Liu; Jingjun, Liu; ... - Journal of Solid State Chemistry

Multi-walled carbon nanotube/cadmium sulfide hybrid heterostructures were easily synthesized by employing a thermal decomposition of thioacetamide as a sulfide-ion source in an aqueous regime. The resulting cadmium-sulfide phase is comprised of a zinc-blende structure of spherical polycrystalline nanoparticles (cadmium-sulfide nanoclusters) with the subunits of ca. 15 nm, deposited on the nanotube surface. The formation of the cadmium-sulfide nanoparticles with zinc-blende structure (cubic crystal) suggests that the local concentrations of reacting ion species in the vicinity of the nanotube surface are different from those in the reaction solution. The cadmium-sulfide nanoparticles are comprised of a stoichiometrically ideal chemical-composition ratio (cadmium: sulfur=1:1.02)more »« less

Photoelectrical, optical, and transport properties of poly (3-hexylthiophene)-zinc sulfide hybrid nanocomposites

Journal Article Singh, Beerandra; Kaur, Amarjeet - Journal of Applied Physics

We have synthesized nanocomposites of poly (3-hexylthiophene) (P3HT) at 273 K and zinc sulfide (ZnS) nanoparticles at 353 K by the chemical route method. The synthesis of these nanocomposites is confirmed by UV-visible, high resolution transmission electron microscope, and Raman spectroscopy. We have measured photocurrent of P3HT using 50 W tungsten lamp. The photoconductivity increases with concentration of ZnS in P3HT-ZnS composite. Temperature dependent dc conductivity of P3HT and its nanocomposites have been thoroughly investigated in light of Mott's variable range hopping.

INTERNAL PHOTOEFFECT AND EXCITON DIFFUSION IN CADMIUM AND ZINC SULFIDES. Technical Report No. 123

Technical Report Balkanski, M; Waldron, R

The spectral response of photoconductivity of ZnS and CdS for both single-crystal and sintered-powder samples was measured for several distances between the area of illumination and the electrode region. The energy transport process for indirect illumination was studied by measuring the photocurrent pulses produced by high intensity light flashes and by experiments with light transmission and electric fields. These studies demonstrate energy transport by electrically neutral entitles other than photons, whlch are interpreted as diffusion of excitons or mobile electron-hole pairs. (auth)
