Abstract:
Carbon forms many allotropes of which graphite and diamond are known
from ancient times and several new ones (fullerenes, nanotubes)
were discovered only in the last 20 years.
The two-dimensional form: graphene was only very recently fabricated
but in the meantime it is a rapidly rising star in materials science.
This atomically thin two-dimensional material exhibits exceptionally high 
crystal and electronic quality. Despite its short history it has already 
resulted
in new physics and potential applications opening up new perspectives for 
carbon based electronics. Electrons in graphene obey a linear dispersion 
relation resulting
in the observation of a number of peculiar electronic properties, e.g. 
anomalous
quantum Hall effect, absence of localization and minimal conductivity.
Due to its unusual electronic spectrum it has led to the emergence
of a new paradigm of relativistic condensed matter physics.
