Exceptional broadband absorption of nanoporous gold explained by plasmonic resonances at dangling ligaments
Muhammad Salman Wahidi, Maurice Pfeiffer, Xinyan Wu +3
Nanoporous gold (npAu) has emerged as a potential candidate for many optical applications exploiting its large surface to volume ratio and high broadband absorption. However, the p…
Energy dependent Chemical Interface Damping induced by 1-Decanethiol Self-Assembled Monolayer on Au(111)
Maurice Pfeiffer, Gregor B. Vonbun-Feldbauer, Jacob B. Khurgin +5
The chemical interface damping (CID) effect increases the collision frequency of free electrons in metals by changes of the metal surface. We have now experimentally disentangled t…
Pulse Compression by an Optical Push Broom On a Chip
Boyi Zhang, Maurice Pfeiffer, Mahmoud A. Gaafar +5
In this study, we report a first experimental demonstration of pulse compression by a gradual refractive index front moving in a periodically modulated silicon waveguide, the so-ca…
Chemical Interface Damping by Electrochemical Gold Oxidation
Maurice Pfeiffer, Xinyan Wu, Fatemeh Ebrahimi +3
Chemical interface damping is a change in the effective collision frequency of conduction band electrons in metal originating from a chemical change of the metal interface. In this…
Size dependent photoemission study by electrochemical coarsening of nanoporous gold
Fatemeh Ebrahimi, Xinyan Wu, Maurice Pfeiffer +4
The generation and utilization of hot charge carriers in plasmonic materials have emerged as a topic of significant importance, with profound implications across multiple disciplin…
