Abstract

Upon the addition of silver nanowires (AgNWs), the electrical conductance of graphene film is improved. According to the film's optical birefringence, as shown by studies using liquid crystals (LCs), the improvements do not result from the chemical doping properties of the AgNWs; instead, they arise because the AgNWs facilitate connections among the domains in the graphene film. This is further supported by the film's Dirac point voltage, Raman spectra, and electrical resistance.
