Abstract:
In developing countries like Kenya, solution processing
technique is the cheapest and simplest technique to grow inorganic
composites thin films. This method was used to grow thin films of
Cd0.3Zn1.1xS0.7 on ordinary microscope Perspex substrate slides from
aqueous solutions of Zinc chloride and cadmium chloride in ammonia
solution. A solution of triethanalomine was used as a complexing
agent while thiourea was used as source of sulphide ions. Electrical
properties as a function of their thicknesses were obtained by varying
deposition time while all other parameters were maintained constant.
Using a resistance measurement device and a Gauss meter, resistivity
and the conductivity of the films were found to be thickness
dependent with semiconductor nature.
