Topic/Area of research: Condensed Matter Physics / Materials Science / Thin films / Ferroelectrics / Optical properties.
Ferroelectrics are more than materials—they are gateways to revolutionizing energy, electronics, and healthcare. If you’re driven to innovate, let’s redefine the future together.
Driving Innovations in Ferroelectrics for Sustainable Technologies
My lab is working on advanced ferroelectric materials to address global challenges in energy, electronics, and healthcare. Key thrusts:
- Freestanding ferroelectric films for transparent, flexible electronics (wearables, foldable displays).
- Electrocaloric cooling and ultrahigh-density capacitors for green energy solutions.
- HfO₂-based thin films with wake-up-free ferroelectricity for next-gen memory devices.
- Bandgap-engineered perovskites for solar energy and optoelectronic applications.
