    Abstract

    The effects of charging on a ZrO2 sintered body due to electron irradiation were investigated by means of electron holography. The charging effects were quantitatively evaluated as a function of the incident electron density. The ZrO2 sintered body was positively charged within a transmission electron microscope. By means of simulations taking into account reference wave modulation due to a long-range electric field, we were able to obtain the amount of charge on the ZrO2 sintered body. Further, fluctuation in the amount of charge on ZrO2 during electron irradiation was found through the presence of an irregular contrast in the reconstructed phase image.
