Nanocrystals (NC) alloyed composite CdSxSe1-x(x=0 to 1) have been prepared using the chemical solution deposition technique. The energy band gap of these alloyed nanocrystals of approximately the same size, have been determined by scanning tunneling spectroscopy (STS) technique at room temperature...
Notably, a photodetector based on CdSxSe1–x nanowalls displays excellent photoelectric performance, such as high responsivity (3 × 102 1 × 103 A/W), high external quantum efficiency (1.01 × 103 2.93 × 103), and fast response speed in the millisecond magnitude. Furthermore, the CdS ...

Glasses doped with CdSxSel−x microcrystallites, which are normally referred to as color filters, display interesting properties. JAIN and LIND [1] reported degenerate four-wave mixing experiments in these samples and observed 8-nspulse-width limited-d
Autocorrelation functions of generation-recombination noise of CdSxSe1-x thin films illuminated by white light are presented. These functions can be described by a sum of exponential terms corresponding to the Lorentzians that represent the spectral density function. For some positions of the quasi-...
In this work, we report the ultrahigh photoconductivity of bandgap-graded CdSxSe1−x nanowires and its detailed analysis by means of ultrafast optical-pump terahertz-probe (OPTP) spectroscopy. The recombination rates and carrier mobility are quantitatively obtained via investigation of the transient ...
