A vacuum-free solution-processed fabrication strategy featuring templated electrodeposition and imprint transfer (TEIT) is developed for micro- and nanoscale metallic structures. Various functional devices, including metal-mesh transparent electrodes and plasmonic sensors, are demonstrated using this cost-effective and scalable manufacturing process.
It is highly demanding to design active nanomotors that can move in response to specific signals with controllable rate and direction. A catalysis‐driven nanomotor was constructed by designing catalytically and plasmonically active Janus gold nanoparticles (Au NPs), which generate an asymmetric temperature gradient of local solvent surrounding NPs in catalytic reactions. The self‐thermophoresis behavior...
We studied the extraordinary light transmission through opaque thin metal film with subwavelength holes blocked by metal disks. The maximum transmission is achieved when the disk diameter is around 80 nm even with different hole diameters.
We study the effects of nanodots on surface plasmons and field enhancement in nano-pillar antenna array (NPA). The NPA's nanodots have slight effect on surface plasmon resonance wavelength, but increase field enhancement by two orders of magnitude.
