  • 3. Nanoscale characterization using scanning probe microscopy.

Research Projects

Title: Towards energy-efficient gallium nitride-based semiconductor for photoactivity enhancement

Gallium nitride-based semiconductors have great potential to hold the future of modern electronic devices. GaN is wide bandgap that can endure higher frequencies and greater voltage, offering efficient charge transfer. We are interested in the nanoscale electric and mechanical phenomenon at gallium nitride-based interfaces.

Title: Ferroelectric materials for photoelectrochemical in electrolyte-oxide system

Ferroelectric polarization shows great potential to boost the efficiency of photoelectrochemical performance with the presence of internal field and domain walls which might favor the separation of photo-excited charges to reduce the likelihood of recombination. We look into controlling the overall redox reaction, and its effect on the charge transfer at solid/liquid interface by tuning the photocatalytic activity with ferroelectricity.
