Heterostructure Nanomaterials
Synthesis and characterization of heterostructure nanomaterials through solid-state reactions. We explore novel growth mechanisms at the atomic scale via in-situ TEM, revealing phase transformations and diffusion behaviors in real time.
Resistive Random-Access Memory
Investigation of resistive switching mechanisms in oxide-based memristive devices, including nanofilament dynamics, multi-level resistance characteristics, and novel device architectures using Kirkendall effect nanotubes.
Liquid Metal
Utilizing gallium-based liquid metals for room-temperature synthesis of 2D oxide semiconductors (Ga₂O₃, Cr₂O₃, CrN), bimetallic MOFs via interface control, and electrochemically driven soft robotics applications.
How do nanomaterials form?
We use in-situ TEM to directly observe atomic-scale growth, diffusion, and phase transformation in real time — revealing mechanisms invisible to conventional characterization.
Can room-temperature synthesis replace high-T processes?
Through liquid metal printing, we synthesize atomically thin oxide semiconductors at ambient conditions — enabling flexible, large-area electronics without energy-intensive fabrication.
What controls resistive switching?
By observing nanofilament evolution in situ, we uncover the fundamental mechanisms governing memory switching — from single-filament to dual-filament behaviors in oxide devices.
Can liquid metals become functional machines?
We explore electrochemically driven liquid metal locomotion for soft robotics, demonstrating remote-controlled movement of EGaIn@Fe composites.
