They have also begun controlling its conductivity. Samsung has made the Graphene equivalent of a switching transistor. Now if they can scale that. All I can think about here are loudspeaker xover capacitors based on the conductivity and properties of Graphene. Create optimum dialectic absorption match and other capacitance tweaks for the high end driver aka AC motor within the crossover circuit. Making it possible to tweak the xover caps directly to the driver and systemic to the circuit.
