Ultrafast thermalization of electrons in metal nanostructures is studied by means of pump-probe spectroscopy. We track in real-time the plasmon resonsance evolution, providing a tool for understanding and controlling gold nanoantennas non-linear optical response.
In this work we investigate the use of Au nanorods as optically actuated electron emitter arrays. We have fabricated high-density arrays of 10 nm diameter Au nanorods via electron beam lithography and studied the effects of, emitter array density on charge yield, and laser intensity on emitter morphology, respectively. Additionally, we have numerically simulated the magnitude of the local electric...
The steering, control or switching of electron wavepackets by light is expected to pave the way towards the much wanted visualization of nanoplasmonic field dynamics or real-time probing of electron motion in solid nanostructures. Electron pulses generated by strong-field tunneling from sharp gold tips irradiated by few-cycle laser pulses and accelerated in the near field are believed to be suitable...
We demonstrate the fabrication of plasmonic nanostructures (rings, split rings, and other structures) by a process involving molding by soft lithography, thin film deposition, and mechanical sectioning (nanoskiving). This unique process is highly parallelizable and allows for the fabrication of nanostructures of multiple materials in the same plane and very high aspect ratio structures. We characterize...
