| Research Abstract |
Glass is known as typical insulator, whose volume and surface resistivities are extremely high. For example, electric current cannot flow practically through a 0.1-1 mm-thick soda-lime glass plate. If the switching of this high resistivity can be controlled, switching devices with huge resistivity would be realized. In this study, employing slow highly charged ion microbeams, we charged a point-like region on a glass plate in vacuum and measured the trajectories of the reflected ions. Analyzing the trajectories taking into account the dynamic charge-up distribution, it turned out that the resistivity depends on the strength of the electric field induced by the charge and shows possibility of a hysteretic switching loop, which was reproduced by a model calculation.
