Graphene is an emerging material, like a rising star on the horizon of physics. Acclaiming the Nobel Prize in physics in 2010, the two dimensional crystal continues to surprise us with new physics as well as new applications that are destined to reach the commercial sphere.



In this lecture series, we have invited Pakistan's two most distinguished scientists to discuss the fundamental physics. The understanding of graphene has opened up new doors of inquiry. What immediately catches our attention is the emergence of new physics: relativistic quantum effects, which previously, are only the ambit of high energy physicists. With graphene, for example, it is now possible to mimick these high energy effects on the tabletop. This lecture series aims at:



* describing relativistic quantum mechanics,
* understanding how the charge carriers in graphene are massless Dirac fermions,
* understanding the electronic structure of this two dimensional material,
* unravelling some of its exciting transport and structural properties, and
* appreciating the role of disorder in graphene.
