Expérimental et théorique
This thesis focuses on the experimental study of the interplay between nanofluidic transport and electronic excitations at the interface between flowing liquids and semiconducting systems. The aim is to explore interfacial coupling processes between fluids and solids. This coupling arises from the coherent energy exchange between the collective modes of the fluid (which we coin ‘hydrons’) and the electronic and lattice excitations – plasmons and phonons – in the confining semiconductors. The coupling between fluids and solids, already validated by experimental and theoretical results in nanofluidics, is opening a new area of investigation at the interface with semiconductor quantum devices that merges today at the same length scale. These nanoscale devices where quantum confinement is an unavoidable ingredient to determine physical properties is the playground where we are going to develop the thesis proposal.
