Castro Neto, Ting Yu, and Elbert E. M. Chia Using terahertz time-domain spectroscopy, the real part of optical conductivity [ σ 1 ( ω )] of twisted bilayer graphene was obtained at different temperatures (10–300 K) in the frequency range 0.3–3 THz. On top of a Drude-like response, we see a strong peak in σ 1 ( ω ) at ∼2.7 THz. We analyze the overall ... [Phys. Rev. Lett. 110, 067401] Published Thu Feb 07, 2013
