    • -1 before they were focused onto the graphene samples. The back-reflected light was collected and detected by a mercury cadmium telluride detector. The samples had a typical lateral dimension around 20 μm. The microscope we used had a 36x reflective objective that confined the infrared beam to a diameter <10 μm on the sample.

    • A small band gap can open in a doped graphene bilayer (20). At our doping level, the bandgap is relatively small and will not affect the qualitative behaviors. In the tight binding calculation described in the text, this gap-opening effect is included in a self-consistent way following (16).

    • The electron density of the Si back gate will also be modulated by electrical gating. It will also contribute to the IR reflectivity change and is described by Drude free-carrier response. However, its contribution is more than an order of magnitude smaller than that of graphene and remains a constant at different dc gate voltages
