Abstract

It has been discussing the use of cadmium sulfide (CdS) as a material for photodetectors. CdS is a direct bandgap II-VI semiconductor with desirable properties for photodetectors, including high sensitivity, fast response time, and wide spectral range from ultraviolet to near-infrared. X-ray diffraction analysis confirmed the cubic crystal structure of the porous CdS thin film. Scanning electron microscopy revealed a porous morphology with macropores ranging from 200-300 nm in size. The performance of the porous CdS photodetector was evaluated. Under visible light illumination, the device generated a photocurrent of 16 nA, with response times of around 5 seconds for both the rising and falling edges of the light-induced current

Abstract

After producing poly orthobromo aniline, FT-IR spectroscopy was used to investigate its structure. We examined the optical and electrical characteristics of poly-o-bromo aniline (o-BrAn) in this work. O-bromoaniline/Ag, an original polymer, has been combined. Several techniques, including FT-IR spectroscopy and UV-visible spectra, have been employed for analyzing the mixer. The nonlinear changes in voltage and current are demonstrated by the I-V characteristics.The conductivity values ranged from o-BrAnp is 5.6×10-8 S/cm , but at o-BrAn/Ag0.25 is 3.1×10-7 S/cm. Since the conductivity value of the material is in the range of semiconductor, it can be used in the field of organic semiconductors.
