Nanoionic Devices for Physical Property Tuning and Enhancement

Nanoionic devices for physical property tuning and enhancement have been developed to generate novel functions overcoming limitations of conventional materials synthesis and semiconductor technology. Local ionic transport near the solid/solid interface enabled in-situ tuning and enhancement of various physical properties. Two electronic carrier doping methods can be used to achieve extremely high-density electronic carriers: one is electrochemical carrier doping using a redox reaction; the other is electrostatic carrier doping using an electric double layer (EDL). Optical bandgap and photoluminescence are tuned for various applications including smart windows and biosensors. Magnetization and magnetoresistance are tuned for low-power-consumption magnetic storage devices. Superconducting transition temperature is enhanced for exploring high temperature superconductivity. Nanoionic devices for physical property tuning and enhancement are promising derivative of atomic switch technology.
