The AFM-Raman System (NT-MDT, Russia) delivers nondestructive analysis of the sample topography, morphology and physico-chemical properties, including measurements of surface potential, elasticity, conductivity, magnetic domains etc. Sample thickness can be measured with an atomic resolution, which allows to distinguish between numbers of atomic layers in 2D nanomaterials. The instrument is also equipped with a precisely aligned Raman microscope, which further allows to perform a correlative imaging of sample topography/morphology and Raman microscopy.
