Through investigation of photoelectron emission from the surface of mica with ultraviolet irradiation, it has been clarified that the surface states of mica play an important role not only in the electron emission but also in the electronic conduction of the surface. To study this in more detail, photothresholds of the electron emission from the surface have been measured for Muscovite mica treated with fast atom bombardment (FAB) under various conditions caused by contact charging generated by contact with a biased conductive brush. In addition, another static approach was performed with corona charging for deposition of charges on the surface of mica. The photothreshold has not been observed for FAB-treated specimens after corona charging. Such a phenomenon is concluded to be caused by the transport of electrons between the conductive brush and the surface states of mica in the range of 5.0 to 5.8 eV. In this paper, we will demonstrate that the surface states of mica are closely related to contact charging as well as to the electronic conduction state of the surface.
