Nanometer-scale microscopy via graphene plasmons

Abstract

Using graphene plasmons (GPs), we can realize a nanometer-scale microscopy. Our scheme takes advantage of the extremely large wave number of GPs and the low loss of graphene. Comparing with conventional nonlinear structured-illumination microscopy based on high-order nonlinearity associated with high intensity light, our proposal only requires linear response. Consequently we need a very weak field, which means less damage to the sample and which may play a significantly important role in the imaging of the biological systems.
