We created polaritonic metalenses in heterostructures formed by hBN and GeSbTe and characterized them with SNOM. The metalenses are created switching the phase of GeSbTe below hBN from amorphous to crystalline, focusing hBN phonon polaritons.

Abstract
We created polaritonic metalenses in heterostructures formed by hBN and GeSbTe and characterized them with SNOM. The metalenses are created switching the phase of GeSbTe below hBN from amorphous to crystalline, focusing hBN phonon polaritons.File in questo prodotto:
