Nonlocal and Nonlinear Plasmonics in Atomically Thin Heterostructures

A new theoretical study published in ACS Nano shows how interactions between electrically tunable graphene and phosphorene nanoribbons can be used to control and selectively enhance nonlinear optical processes at the nanoscale.

In this publication, the groups use mid-infrared phonon-polaritons in hexagonal boron nitride (hBN) screened by monocrystalline gold flakes to push the limits of light confinement unobstructed by nonlocal phenomena, even when the polariton phase velocity approaches the Fermi velocities of electrons in gold.

On the edge of obsession

Please meet Professor Antonio Fernández Domínguez (Otto Mønsted Visiting Professor at POLIMA) for a talk about how he ended up being a Professor in Physics and why online meetings are not enough to establish meaningful collaborations.
