CdMnS DMS thin films: Synthesis, Structural and Transport Characteristics

Abstract
Cd1-xMnxS thin films with x value ranging between 0 to 0.5 were deposited onto the glass substrates using a chemical deposition process. The composition of the as- grown samples was determined by an EDS technique. The polycrystalline growth resulted over the whole range studied and both CdS and Cd1-xMnxS films exhibited hexagonal wurtzite structure with growth orientation along (101) direction. Typically, the lattice parameter ‘a’ decreased from 4.131A0 to 4.110A0 for the change of x from 0 to 0.1 and thereafter it returned to its original value. Similar changes in c with x were also observed (6.710 A0 to 6.688 A0). Average crystallite size increased with increase in x from 0 to 0.1 and then decreased for further increase in x. The electrical conductivity is found to be enhanced with x upto 0.01 and then decreased with further increase in x. The activation energies were calculated in both the conduction regions. The transport characteristics such as thermoelectric power, carrier concentration (n), mobility (), and barrier height (b) were studied as a function of the working temperature and materials composition and attempted to correlate with the observed changes in structural characteristics.
