Strongly bound excitons dominate electronic relaxation in resonantly excited twisted bilayer graphene
Hiral Patel, Lola Brown, Yufeng Liang +3
When two sheets of graphene stack in a twisted bilayer graphene (tBLG) configuration, the resulting constrained overlap between interplanar 2p orbitals produce angle-tunable electr…

New Mechanism for Strongly Bound Excitons in Gapless Two-Dimensional Structures
Yufeng Liang, Ryan Soklaski, Shouting Huang +4
Common wisdom asserts that bound excitons cannot form in high-dimensional (d>1) metallic structures because of their overwhelming screening and unavoidable resonance with nearby co…

Van Hove Singularities and Excitonic Effects in the Optical Conductivity of Twisted Bilayer Graphene
Robin W. Havener, Yufeng Liang, Lola Brown +2
We report a systematic study of the optical conductivity of twisted bilayer graphene (tBLG) across a large energy range (1.2 eV to 5.6 eV) for various twist angles, combined with f…
