AbstractThe purpose of this study is to build and validate a model of volume resistivity from the experimental results to analyze the influence of parameters such as electron beam energy and sample temperature. We established a measurement setup, called the charge storage method, which measures volume resistivity by analyzing the time history of a dielectric devices to investigate volume resistivity in the temperature range attained (from 260K to 320K). In this paper, we measured the volume resistivity. We analyzed the effect of sample thickness, electron beam irradiation energy and temperature. The dielectric material considered here is typical polyimide (Kapton(Reg. U.S.Pat. & Tm. Off.)) film. The experimental results indicate that higher electron energy and thinner sample thickness show lower resistivity .volume resistivity in dark current region decreases theoretically as the sample temperature increases. Moreover, we proposed the mechanism of charge accumulation in charge storage method.
