Extensive research has been done during the last two decades on cadmium sulfide (CdS) thin films, mainly due to their application to large area electronic devices such as thin film field-effect transistors (Schon et al., 2001) and solar cells (Romeo et al., 2004). For the latter case, chemical bath deposited (CBD) CdS thin films have been used extensively in the processing of CdTe and Cu(In,Ga)...

A photoluminescent II-VI group semiconductor nanocrystal (NC)-based signaling platform composed of thioglycolic acid capped CdS NCs and acetylcholinesterase-acetylthiocholine enzyme catalytic reaction system was developed that was shown to be highly sensitive to nerve agents and toxic organophosphate pesticides with detection limits down to sub-nM levels. This new sensing protocol does not requ...

– Chalcogenide is a proven phase change material used in re-writeable CDs and DVDs. This material changes phases, reversibly and quickly, between an amorphous state that is dull in appearance and electrically high in resistance, and a polycrystalline state that is highly reflective and low in resistance. The application of this commercially proven technology to create dense, high-speed, non-vol...

In this paper, ultrasonic irradiation was applied for the synthesis of K2Ti6O13 nanobelts and novel nanocomposite (PbS-CdS/Ti6O13) through ion exchanging and co-intercalation processes. Thirty minutes of ultrasonic irradiation caused the formation of pure, uniform potassium hexatitanate with smaller particle size. The incorporation of PbS and CdS nanoparticles into the layers and on the surface...

The piezo-phototronic effect is about the use of the piezoelectric potential created inside some materials for enhancing the charge carrier generation or separation at the metal-semiconductor contact or pn junction. In this paper, we demonstrate the impact of the piezo-phototronic effect on the photon sensitivity for a ZnO-CdS core-shell micro/nanowire based visible and UV sensor. CdS nanowire ...

Abstract The wurtzite (wz) structure of CdS is analysed using density functional theory within the generalized gradient approximation (GGA) and Hubbard correction (GGA+U). total energy convergence evaluation carried out concerning cut-off (ecutwfc) k-point sampling. geometry optimization wz-CdS calculated force minimization process, which based on Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorit...

Natural dyes obtained from plants, vegetables and fruits are widely studied and tested as low cost sensitizer for dye sensitized solar cell ( DSSC) in order to replace the rare and expensive inorganic and organic sensitizers. Although, many works have been done using TiO2, ZrO2, ZnO etc. as the nanoporous semiconductor, little importance was given to the use of CdS thin film as a cost effective...
