Theoretical EELS of GNR edges
What is it about?
Grapheme nano ribbons (GNR) are atomic sized strips of graphene with important device applications. In this paper we present a systematic theoretical study of the different edge structures and simulate the effect of an atomic resolution electron energy loss spectroscopy experiment. EELS is a useful probe of the local atomic environment but can easily hard to interpret. We show which atomic structures give rise to which features in EELS and hence provide a set of spectral fingerprints.
Why is it important?
Grapheme nano ribbons (GNR) are atomic sized strips of graphene with important device applicIons. The atoms at the edges have a different environment compared to the inside of the ribbon and hence have different properties. This paper provides different spectral fingerprints for different edge structures so that experiments can unequivocally determine which edge sites are present in any sample.
