Central role of domain wall depinning for perpendicular magnetization switching driven by spin torque from the spin Hall effect
O. J. Lee, L. Q. Liu, C. F. Pai +4
We study deterministic magnetic reversal of a perpendicularly magnetized Co layer in a Co/MgO/Ta nano-square driven by spin Hall torque from an in-plane current flowing in an under…
Transient absorption and photocurrent microscopy show hot electron supercollisions describe the rate-limiting relaxation step in graphene
Matt W. Graham, Su-Fei Shi, Zenghui Wang +3
Using transient absorption (TA) microscopy as a hot electron thermometer we show disorder-assisted acoustic-phonon supercollisions (SCs) best describes the rate-limiting relaxation…
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…
