                  Abstract

Superconductivity, as one of the fundamental manifestation of quantum
physics, refers to the formation of the so called Cooper pairs between two
electrons with opposite spin and equal but opposite momentum, when a weak
attractive interaction exists between the electrons. Until recently, most of
studies on electronic superconductivity were focused on
Bardeen-Cooper-Schrieffer (BCS) limit in ordinary electronic material with
large chemical potential whereas the electrons, as non-relativistic
particles, occupy essentially parabolic energy bands. In this respect, the
question of superconductivity for relativistic electrons was remained
unanswered. The recent discovery of graphene, in which electrons at low
energies behave like massless Dirac fermions with a pseudo-relativistic
chiral property, has made this question of particular importance and
relevance. Very recently, this has created a tremendous interest in
experimental and theoretical study of superconductivity and its associated
proximity effect in graphene materials. These studies has led to
new fundamental physics as well as novel phenomena with potential
applications. In this talk, I will present results obtained in some of
these studies.
