Abstract
Quantum interference by electronic waves very significantly influences the quantum transport and hence the electronic properties in nano-materials. Graphene, in which the Dirac fermions play an important role in transport, is studied through one such transport parameter e.g. conductance. Graphene quantum dot of two different shapes and sizes are considered for the study. The conductance is seen to oscillate with electron energy. Size of the ballistic leads also affects the size of the oscillations.
