Abstract

Abstract : Intrinsic plasmo-electronic properties of monolayered NP arrays are measured without substrate's influence opening a route for promising sensing or hyperthermia applications. Abstract : We report on photo-current generation in freestanding monolayered gold nanoparticle membranes excited by using a focused laser beam. The absence of a substrate leads to a 50% increase of the photo-current at the surface plasmon resonance. This current is attributed to a combination of trap state dynamics and bolometric effects in a nanocomposite medium yielding a temperature rise of 40 K.
