Popis: Nanoscale light manipulation and characterization are essential in nano-optics, but conventional microscopy or indirect imaging methods are often limited by low resolution or invasive nature. Here, a non-destructive light-field imaging with ~20 nm resolution is realized by p-n junction photodetection in graphene controlled by gate voltage.
