Paper Title
Hetero Junction Photodiode for Graphene Doped Tio2/P-Silicon

Abstract
The photo response properties of Al/p-Si/GO:TiO2/Au diodes were investigated using transient photocurrent and conductance spectroscopy techniques. The average barrier height and ideality factor values of the diodes were found to be 0.601 ± 0.001 eV and 17.9.3 ± 9. It is seen that the electronic parameters of the diodes depend on GO content. The obtained ideality factor is higher than unity due to the low carrier mobility of the organic interlayer. The change in the capacitance of the diodes indicates a continuous distribution of interface states. The photo response properties of the diodes are changed with GO content. Al/p-Si/GO: TiO2/Au having 3% GO weight exhibited the highest photosensitivity. The obtained results indicates that the prepared photodiodes can be used as a photo sensor in optoelectronic device applications.
