The prepared thin films then deposited onto glass as well as metallic substrates. The glass substrate was cleaned in aquaregia, washed in distilled water and isopropyl alcohol (IPA). These prepared samples were then subjected for the electrical measurements by employing Keithley electrometer. In PANI/ CdS junction the conduction of charge across the junction is typically a mixture of electron from n-CdS side a polaron and bipolaron from p-Pani side.…show more content…
Thermal and environmental stability of the synthesized sample of PANI is investigated by measuring the thermal transport properties of the samples at different temperatures and time using Transient Plane source (TPS) technique. The results indicate that the PANI shows excellent thermal and environmental stability. Chemically prepared Cadmium Sulphide has been printed on a pallet of conducting Polyaniline (of 1.2 cm diameter and 2 mm thickness). This pallet of CdS coated conducting Polyaniline has been sintered at 150° for six hours for ensuring better adhesion. The I-V characteristics of CdS, conducting Polyaniline and CdS coated conducting Polyaniline have been recorded at room temperature using
