dc.description.abstract On-surface isolation of few-layer antimonene by micromechanical exfoliation leads to nanoflakes with a variety of thicknesses. Whereas Raman spectroscopy fails to provide information, the optical properties of the antimonene thin flakes allow a simple and quite accurate identification of the different thicknesses on the basis of the optical contrast. We measured the optical contrast of flakes using different illumination wavelengths in the visible spectrum and their thicknesses using atomic force microscopy. The optical contrast was then quantitatively accounted for by a Fresnel-law-based model yielding the refractive index and absorption coefficient of these thin crystals in the visible spectrum. Hence, the optical microscopy data can be quantitatively analyzed to determine the thickness of the flakes in a fast and nondestructive way that will be useful for future nanodevice fabrication en_US
