Authors

Abstract

In this research, FTO conductive and transparent thin layers were deposited
on glass substrates by using spray technique. Effect of solution volume
(layers thicknesses) and fluorine doping on layers electrical and optical
properties is studied. Their nanostructures morphology and growth
mechanism are investigated by SEM images. Optical transmission spectrum
is obtained by Optics Ocean spectrometer and surface resistance of layers
are measured by Four Probe method .The optimum conductive transparent
layer which has maximum transmission coefficient and minimum Resistivity
in film Thickness effect for 830 nm Thickness with 0.26×10 -3 Ω.cm surface
resistance and 60% optical transmission in visible range and in doping
effect for sample with 1.2 HF concentration with 1.19×10 -3 Ω.cm Resistivity
and %84 optical transmission have been measured. The obtained results for
surface resistance are noticeable with others results.
