Abstract:
This thesis investigates the manipulation of the properties of Indium Tin
Oxide (ITO) coatings. This is carried out with a combination of Experimental
and Theoretical work. The coating of ITO onto a glass substrate was both
theoretically modelled and the practical work analysed to observe the
effects. Observation of the effects on the output parameters when
depositing a single layer of ITO via Electron beam evaporation onto a glass
substrate multiple times with varying conditions was carried out. The
amount of ITO required to produce optimum % transmission and the
deposition conditions required to provide <20 7/▢ and <100 7/▢ were
investigated.
This study then considered the addition of a single layer of an additional
coating both theoretically and practically to maximise the %T for the
wavelength ranges under consideration. From this, the ideal refractive index
for the additional coating to maximise the %T for the ranges was deduced.
Progression was then made to consider multiple layers. Theoretical work
carried out on the addition of extra layers and the deduction of the optimal
refractive index implied that overall, Cryolite would produce the best
average %T across the ranges considered.
In addition to this, the results of ITO deposition via Evaporation and
sputtering were examined to determine the difference the technique used
has upon the coating produced.
