Abstract
The deposition of ZnO thin films on Poly Propylene Carbonate (PPC) plastic
substrates and their characterizations for the purpose of fabricating ZnO metalsemiconductor-
metal UVA photodetectors (MSM UVA PDs) have been performed
and the fundamental properties of the fabricated UVA PDs have been studied.
The objectives of this study can be divided into two main phases; the first main phase
can be divided into two sub-phases; the first sub-phase is to study the structural,
optical and electrical properties of the deposited ZnO thin films on PPC, glass and Si
substrates by direct-current (DC) sputtering technique. The second sub-phase is to
investigate the resultant structural, optical and electrical properties of the deposited
ZnO thin films with different thicknesses onto PPC substrates.
The second main phase also can be divided into two sub-phases; the first subphase
is to investigate the feasibility of ZnO MSM UVA photodetectors fabricated
with various metal contacts i.e. Pd, Ni and Pt using PPC plastic as a substrate and
compared the behavior the three PDs. The second sub-phase is to study and compare
the performance of the PDs under different applied voltages.
The results in the first main phase showed that the properties of the deposited
ZnO thin films on PPC are better than those prepared on glass and Si, also the
increased in ZnO thin film thickness from 0.3 to 1.0 m resulted in the improvement
of the structural and optical properties.
