Plasmonics in composite nanostructures
Plasmonics is a rapidly developing research field with many potential applications in fields ranging from bioscience, information processing and communication to quantum optics. It is based on the generation, manipulation and transfer of surface plasmons (SPs) that have the ability to manipulate light at the nanoscale. Realizing plasmonic applications requires understanding how the SP-based pro...
متن کاملBallistic composite fermions in semiconductor nanostructures.
We report the results of two fundamental transport measurements at a Landau level filling factor ν of 1/2. The well known ballistic electron transport phenomena of quenching of the Hall effect in a mesoscopic cross-junction and negative magnetoresistance of a constriction are observed close to B = 0 and ν = 1/2. The experimental results demonstrate semi-classical charge transport by composite f...
متن کاملAlignment enhanced photoconductivity in single wall carbon nanotube films.
In this paper we report, for the first time, the alignment enhanced photoconductivity of single wall carbon nanotube films upon laser illumination. The photoconductivity exhibited an increase, decrease or even 'negative' values when the laser spot was on different positions between contact electrodes, showing a 'position' dependent photoconductivity of partially aligned films of carbon nanotube...

متن کاملSurface plasmon resonance enhanced photoconductivity in Cu nanoparticle films.
We describe an all-electrical plasmon detection based on the near field coupling between plasmons and percolating electrons. It is the technique to electrically detect the local field enhancement from randomly distributed Cu nanoparticles coupled to a plasmon resonance. In addition, we revealed that plasmon-sensitivity is maximized at the percolation threshold, the minimum Cu particle surface c...
