Terahertz conductivity of twisted bilayer graphene
Using terahertz time-domain spectroscopy, the real part of optical conductivity [ σ1(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 σ1(ω) at ~2.7 THz. We analyze the over...
