Outline of Research at the Start

Based on the strong coupling photoelectrode, the applicant proposes to employ a p-type semiconductor to develop a photocathode under the modal strong coupling conditions for efficient photochemical reaction, such as carbon dioxide reduction and investigate the dynamics of plasmon-induced hot-holes in the p-type semiconductor using a femtosecond laser pump-probe transient spectroscopy.
