Stacking, Strain, & Twist in 2D Materials Quantified by 3D Electron Diffraction
Suk Hyun Sung, Noah Schnitzer, Lola Brown +2
The field of two-dimensional (2D) materials has expanded to multilayered systems where electronic, optical, and mechanical properties change-often dramatically-with stacking order,…
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…
Oxidation resistance of graphene-coated Cu and Cu/Ni alloy
Shanshan Chen, Lola Brown, Mark Levendorf +9
The ability to protect refined metals from reactive environments is vital to many industrial and academic applications. Current solutions, however, typically introduce several nega…
