Abstract

ZnxCd1-xS (0 less than or equal to x less than or equal to 1) thin films have been deposited by the dip technique on glass substrates. In this method, a clean substrate was dipped into an alcoholic solution ofthe corresponding nitrates and thiourea and then withdrawn verticallyat a controlled speed, and finally baked in a furnace. X-ray diffractometric study suggests that for zinc atomic fraction x less than or equal to 0.6 films prepared at a baking temperature of 500 degrees C arehomogeneous with a hexagonal (wurtzite) structure. Increase in the proportion of zinc in the starting solution is found to produce a decrease in the lattice parameter. SEM studies reveal an increase in grain size with x up to a value of 0.6. For x > 0.6, the films appear to havean amorphous character, as no distinguishable peaks can be seen in the X-ray diffractograms. The SEM micrographs also do not show any clearly defined grains over this range. Values of bandgap obtained from optical absorption measurements as well as from spectral response of photoconductivity are in good agreement with each other and vary monotonically from 2.30 eV (CdS) to 2.69 eV (Zn0.6Cd0.4S) over the range 0 lessthan or equal to x less than or equal to 0.6.
