Abstract

In this study, we studied the nature of thin films formed by holographic photodoping chalcogenide thin films with for use in programmable metallization cell devices(PMC), a type of ReRAM. We formatted straight conduction pathway from the internal interferences of the diffraction gratings which is builded by the holographic lithography method. We investigated the resistance change of solid-electrolyte chalcogenide thin films varied in the applied voltage bias direction from about $1\;M{\Omega}$ to several hundreds of $\Omega$. The switching characteristics of the devices applied holographic lithography method was more improved than ultraviolet exposure condition. As a result of improved resistance change effects, we can analogize that the diffraction gratings is a kind of pattern for straight conduction pathway formation inside the chalcogenide thin films.
