Quantum spectroscopy of plasmonic nanostructures
We use frequency entangled photons, generated via spontaneous parametric down
conversion, to measure the broadband spectral response of an array of gold
nanoparticles exhibiting Fano-type plasmon resonance. Refractive index sensing
of a liquid is performed by measuring the shift of the array resonance. This
method is robust in excessively noisy conditions compared with conventional
broadband transmission spectroscopy. Detection of a refractive index change is
demonstrated with a noise level 70 times higher than the signal, which is shown
to be inaccessible with the conventional transmission spectroscopy. Use of low
photon fluxes makes this method suitable for measurements of photosensitive
bio-samples and chemical substances.Comment: 11 pages, 5 figure
Electrical characteristics of amorphous iron-tungsten contacts on silicon
The electrical characteristics of amorphous Fe-W contacts have been determined on both p-type and n-type silicon. The amorphous films were obtained by cosputtering from a composite target. Contact resistivities, pc=1×10^−7 and pc=2.8×10^−6, were measured on n+ and p+ silicon, respectively. These values remain constant after thermal treatment up to at least 500°C. A barrier height, φBn=0.61 V, was measured on n-type silicon
