Optical multi-characterization platform for two-dimensional materials

Description

Based on a Raman and photoluminescence spectrometer with motorized stage (Horiba, Labram HR), we plan to install a second harmonic generation (SHG) acquisition module. This specific module will enable fine characterization of the symmetry properties of two-dimensional (2D) materials in order to differentiate certain polytypes or heterostructures, and generate spatial maps of the samples.
