Abstract
Pure Zinc Selenide thin films were produced onto the glass micro-slides and stainless-steel substrates as well employing chemical bath deposition method by optimising the preparation and deposition parameters. The concentration of Cadmium (x) in Zinc selenide lattice was changed from 0 to 1. The structural and surface morphological properties of these as deposited thin films were investigated and studied utilising XRD and SEM techniques respectively. These as deposited thin films were poly-crystalline in character and exhibit cubic phase for 0 ≤ x ≤ 0.3 and distinct/mixed phases of cubic and hexagonal wurtzite structures were observed for the 0.4 ≤ x ≤ 0.8 region. Thereafter, again cubic phase seems to be prevailing.The electrical conductivity increased with increase in composition × at the ambient temperature and at higher temperature as well. The thermoelectric power measurements revealed that these semiconducting thin films exhibit ‘n’ type conductivity.
