Chalcogenide glass-based programmable metallization cell (PMC) devices undergo Ag+-ion transport and controlled resistance change under the application of electrical bias. In this paper, photo-doped PMC devices are characterized with impedance spectroscopy. Photo doping is an important step in PMC fabrication as it introduces the mobile Ag into the electrolyte and, therefore, has a significant effect on device characteristics. Data obtained from measurements on devices with different areas in both their high resistance state (HRS) and low resistance state (LRS) are used to parameterize equivalent circuit models. The models elucidate the differences in the HRS and LRS electrical properties.
