| Research Abstract |
We have developed a new apparatus that enables laser exposure to specimens within a transmission electron microscope, and established the methods for analyzing photoexcitation phenomena via electromagnetic field visualization using electron holography. These methods have revealed the process of laser-induced change in the carrier density in an organic photoconductor, in addition to the charging phenomena and/or magnetization process in other advanced materials.
