Abstract
A method for chemical identification of a sample having nanostructures includes the steps of irradiating the surface at wavelengths for each of a first and a second of the nanostructures that are uniquely absorbed by each of the first nanostructure and the second nanostructure such that each is excited to modulate at a first or a second nanostructure frequency, respectively. The method continues with the steps of irradiating the surface with electron beams incident on each of the first and second nanostructure, wherein at least one of secondary electrons, backscattered electrons and transmitted electrons are modulated at the frequency corresponding to each of the first and second nanostructure frequencies. A chemical map of the sample at an atomic scale is then created. A microscope is provided to carry out the method.
