In the past, the electrochemical instability of III–V semiconductors has severely limited their applicability in photocatlaysis. As a result, a vast majority of the research on photocatalysis has been done on TiO2, which is chemically robust over a

We fabricate arrays of metallic nanoparticle dimers with nanometer separation using electron beam lithography and angle evaporation. These “nanogap” dimers are fabricated on thin silicon nitride membranes to enable high resolution transmission el

Integrating plasmon resonant nanostructures with photocatalytic semiconductors shows great promise for high efficiency photocatalytic water splitting. However, the electrochemical instability of most III-V semiconductors severely limits their applica

We have recently demonstrated plasmonic enhancement of several photochemical processes (water splitting, CH4 formation from CO2, methyl orange decomposition, and CO oxidation) by integrating strongly plasmonic metal nanostructures with strongly catal

A systematic study of the mechanisms of Au nanoparticle/TiO2-catalyzed photoreduction of CO2 and water vapor is carried out over a wide range of wavelengths. When the photon energy matches the plasmon resonance of the Au nanoparticles (free carrier a

By integrating strongly plasmonic Au nanoparticles with strongly catalytic TiO 2 , we observe enhanced photocatalytic decomposition of methyl orange under visible illumination. Irradiating Au nanoparticles at their plasmon resonance frequency creates

We report plasmon enhanced absorption in dye sensitized solar cells (DSSC) over a broad wavelength range. 45% enhancement in the power conversion efficiency is observed with the inclusion of plasmonic gold nanoparticles (NPs). Photocurrent spectra sh

Thin Au films (~5 nm) are known to form island-like structures with small gaps between the islands, which produce intense electric field "hot spots" under visible illumination. In this work, we perform finite difference time domain (FDTD) simulations
