Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

Advanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC

Advanced Materials Interfaces, EarlyView.
We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...
