Study of frequency dependent characterization: applied gamma-ray irradiation on metal-polymer nanostructure

The study analyzed the effects of gamma-ray irradiation and high frequency on metal-polymer-semiconductor (MPS). The MPS structure is analyzed before and after gamma radiation source with dose of 30 kGy and 60 kGy, and the impacts of 60Co gamma-ray irradiation on the electrical characteristics of Al/Coronene/p-Si schottky diode have been reported. It has been found that barrier height, the series resistance and the density of the interface trap states strongly depend on applied gamma irradiation dose and also the value of high frequency.
