研究目的
To demonstrate a nanoscale solid-state proton switch for electrical control of optical properties through electrochemical hydrogen gating, enabling tunability of device characteristics such as transmittance, interference color, and plasmonic resonance.
研究成果
The study successfully demonstrated all-solid-state thin film devices with electrochemically switchable optical properties through hydrogen loading/unloading. The approach allows for highly localized optical modulation and has potential applications in plasmonic devices and active metamaterials.
研究不足
The switching speed of devices with hydrogen-switched metallic layers is limited by the hydrogenation/dehydrogenation process. Device cyclability can be affected by dielectric breakdown of the GdOx layer.
1：Experimental Design and Method Selection:
The study utilized a nanoscale solid-state proton switch for electrochemical hydrogen gating to control optical properties. Thin film stacks were grown using magnetron sputtering, and devices were patterned with shadow masks or electron beam lithography.

3：List of Experimental Equipment and Materials:
Magnetron sputtering system, electron beam lithography setup, Keithley 2400 Sourcemeter, CRAIC microspectrometer, and X-ray absorption spectroscopy (XAS) at the Coherent Soft X-ray Scattering (CSX) beamline.
4：Experimental Procedures and Operational Workflow:
Devices were subjected to gate voltage applications in different gas environments. Optical and XAS measurements were conducted to observe changes in transmittance, reflectance, and chemical state.
5：Data Analysis Methods:
Transfer matrix method and finite-difference time-domain (FDTD) simulations were used to model reflection spectra and plasmonic responses.
