Graphene and related 2D semiconductors, owing to their exquisite optoelectronic and mechanical properties, hold great promise as active materials in flexible electronics applications and devices. In this work, we report the use of Laser Induced Forward Transfer (LIFT) for the precise and micro-scale printing of graphene pixels on conventional and flexible substrates in a single step process. Complementary to the experimental studies, Density Functional Theory (DFT) is also employed to investigate the interactions between graphene and metallic substrates (Cu, Ni) as well as to shed light on the energy that is required to detach and deposit intact graphene pixels.
