Raman spectroscopy in two-dimensional materials

Since the discovery of graphene, two-dimensional materials — crystals consisting of a single- or few-layer of atoms — gained considerable interest through their rich potential and promising applications. Raman spectroscopy is a versatile non-desctructive technique in material science. It can be used not only to identify materials, but to investigate their electric and vibrational properties as well. Our group uses first principles methods to model such structures and simulate their spectra.
