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…
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…
Strain Solitons and Topological Defects in Bilayer Graphene
Jonathan S. Alden, Adam W. Tsen, Pinshane Y. Huang +5
Spontaneous symmetry-breaking, where the ground state of a system has lower symmetry than the underlying Hamiltonian, is ubiquitous in physics. It leads to multiply-degenerate grou…
