Electron Holography on Charging Effect in Non-Conductive Materials
The charging effects on non-conductive materials due to electrons irradiation were investigated by electron holography. The phenomena that the charging effects were more enhanced with an increase in the incident electron density were visualized through the direct observations in the electric potential distribution around the specimens. In addition, through the comparison between the electron holography results and the simulations, we were able to obtain the quantitative results indicating the amount of charges accumulated during electron irradiation.
