Abstract
The first seed for the begin of this internship, and the following PhD project, comes from previous works about a still mysterious water-carbon friction mechanism: it has been demostrated that water can interact directly with the carbon's electron, a quantum phenomena that has no precedent in fluid dynamics. On the base of this first observations, a quantum friction mediated current generation mechanism has been studied theoretically. 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 –first with graphene, following previous experiments and then with confining semiconductors.
The coupling between fluids and solids is opening a new area of investigations at the interface with semiconductor quantum devices that merges today at the same length scale
