Abstract:
|
In the present work, structural, optical and electrical properties of indium
sulfide are tuned by specific and controlled doping. Silver, tin, copper and chlorine
were used as the doping elements. In2S3 thin films for the present study were prepared
using a simple and low cost “Chemical Spray Pyrolysis (CSP)” technique. This
technique is adaptable for large-area deposition of thin films in any required shape and
facilitates easiness of doping and/or variation of atomic ratio. It involves spraying a
solution, usually aqueous, containing soluble salts of the constituents of the desired
compound onto a heated substrate. Doping process was optimized for different doping
concentrations. On optimizing doping conditions, we tuned the structural, optical and
electrical properties of indium sulfide thin films making them perform as an ideal
buffer layer. |
