The chain extender-PA6 dosage was kept constant at 1 wt% deemed to be sufficient from previous work [10], noting that the stochiometry of the polymer chain extension reaction is such that very little chain extender is required.
Then aqueous solution of Zn[Cl.sub.2] corresponding to 0.006 mole have been added into the above mixture, to prepare Zn doped CdS thin films with the stochiometry of various concentrations Cd.
By the disparity of composition in this way we can control the stochiometry of these types of compound semiconductors while tailoring their bandgaps with the replacement of Cd by Zn which later on will be proved to be the one of cheaper and easier techniques.
