A Hierarchical 3D TiO2/Ni Nanostructure as an Efficient Hole-Extraction and Protection Layer for GaAs Photoanodes

Michael Graetzel, Hyeonho Jeong

Photoelectrochemical (PEC) water splitting is a promising clean route to hydrogen fuel. The best-performing materials (III/V semiconductors) require surface passivation, as they are liable to corrosion, and a surface co-catalyst to facilitate water splitti ...

Dispersion and shape engineered plasmonic nanosensors

Hyeonho Jeong

Biosensors based on the localized surface plasmon resonance (LSPR) of individual metallic nanoparticles promise to deliver modular, low-cost sensing with high-detection thresholds. However, they continue to suffer from relatively low sensitivity and figure ...

Active Nanorheology with Plasmonics

Tian Qiu, Hyeonho Jeong

Nanoplasmonic systems are valued for their strong optical response and their small size. Most plasmonic sensors and systems to date have been rigid and passive. However, rendering these structures dynamic opens new possibilities for applications. Here we d ...

Programmable chiral nanocolloids

Hyeonho Jeong

Nanoparticles promise a variety of application in energy, medicine, and biology. However, most nanoparticlesâ material composition and shape cannot be tuned and so functions have thus far been limited. Moreover they are often also chemically unstable in ...

Magnesium plasmonics for UV applications and chiral sensing

Hyeonho Jeong

We demonstrate that chiral magnesium nanoparticles show remarkable plasmonic extinction- and chiroptical-effects in the ultraviolet region. The Mg nanohelices possess an enhanced local surface plasmon resonance (LSPR) sensitivity due to the strong dispersi ...
