چکیده

This study is related to fabrication and characterization of redox conductive bridge memristors (RCBM). An active region in RCBM is formed by chalcogenide glass (ChG) doped with silver (Ag). We report the application of plasma enhanced chemical vapor deposition (PECVD) method for depositing ChG films which gives the advantage of flexibility in the composition and structure not easily achieved with sputtering or thermal evaporation. The growth kinetics of the deposition process, as well as the properties of the films is investigated. Optimal deposition conditions for reliable device performance are determined. The electrical characteristics of the devices fabricated at these conditions are also tested. Keywords—Redox conductive bridge memristors; chalcogenide glass; silver; solid electrolyte; film and device characterization

Self-assembled oxide films with tailored nanoscale ionic and electronic channels for controlled resistive switching

Resistive switches are non-volatile memory cells based on nano-ionic redox processes that offer energy efficient device architectures and open pathways to neuromorphics and cognitive computing. However, channel formation typically requires an irreversible, not well controlled electroforming process, giving difficulty to independently control ionic and electronic properties. The device performan...
