Control of the Dirac point in graphene by UV light
Journal article, 2014

It is experimentally shown that the initially shifted Dirac point in graphemeondielectric devices can be brought to zero by illuminating the samples with UV light.This is much easier to accomplish compared to the common procedure of annealing at high temperature. Internal photoemission is concluded to be responsible for the observed effect.
