Dr Cinzia Casiraghi: News from the graphene’s pot

The electronic properties of graphene can be significantly altered by placing it on top of hexagonal boron nitride (another material that has the same type of honeycombed structure as graphene) because of the emergence of new “Dirac points” at an energy determined by the rotational angle between the two materials. The group of Dr Casiraghi, in collaboration with colleagues at the Université Paris-6, has found a simple way to measure the energy of the new Dirac points by using Raman spectroscopy. 

The work has been published on Nano Letters (Eckmann et al, 2013, 13 (11), pp 5242–5246) and was featured in Nanotechweb.org website.
