Research Projects
Our Current Focus
Device Integration
Applying the knowledge of nanophotonics, semiconductor physics, and photoelectrochemistry, the devices capable of catalyzing useful chemical reaction including CO2 reduction and N2 fixation can be realized.
Photonic Design
By careful engineering of nanostructure, the light can be coupled, guided, or redirected as needed. Nanofabrication and optical measurement would be performed to validate the design.
in-situ Spectroscopy
The catalyst transformation and reaction mechanism are of central importance for bridging the knowledge from nanoscale catalysts to practical photoelectrochemical reactions. in-situ spectroscopy will be used to understand the real-time evolution of the catalytic surface/intermediate/product during operation under light illumination and/or electrical bias with high spatial resolution.
Interface Study
The electronic properties of the interfacial layers are critical. Favorable band alignment can promote carrier transport and inhibit voltage drops. Defect and interfacial reaction assisted conduction mechanism will be studied.
