Spin lifetime anisotropy in graphene induced by the SiO2 interface
Aron W. Cummings, Chunhao Guo, Andrew Grieder +5
Understanding how common dielectric substrates influence the spin transport properties of graphene is essential for advancing graphene-based spintronic technologies. Here we use a…
Phonon-Assisted Radiative Lifetimes and Exciton Dynamics from First Principles
Chunhao Guo, Gabriele Riva, Jacopo Simoni +2
Exciton-phonon interactions play a fundamental role in phonon-assisted radiative recombination and exciton dynamics in solids. In this work, we present a first-principles framework…
Magnetic-field dependence of spin-phonon relaxation and dephasing due to g-factor fluctuations from first principles
Joshua Quinton, Mayada Fadel, Junqing Xu +4
The electron spin decay lifetime in materials can be characterized by relaxation (T1) and irreversible (T2) and reversible (T2*) decoherence processes. Their interplay leads to a c…
Spin Dynamics in Hybrid Halide Perovskites -- Effect of Dynamical and Permanent Symmetry Breaking
Kejun Li, Junqing Xu, Uyen N. Huynh +7
The hybrid organic-inorganic halide perovskite (HOIP), for example MAPbBr3, exhibits extended spin lifetime and apparent spin lifetime anisotropy in experiments. The underlying mec…
Spin Relaxation and Diffusion in Monolayer 1T'-WTe from First-Principles
Junqing Xu, Hiroyuki Takenaka, Andrew Grieder +3
Understanding spin relaxation in topological systems such as quantum spin-hall (QSH) insulator is critical for realizing coherent transport at high temperature. WTe, known as…
Ab-initio predictions of spin relaxation, dephasing and diffusion in solids
Junqing Xu, Yuan Ping
Spin relaxation, dephasing and diffusion are at the heart of spin-based information technology. Accurate theoretical approaches to simulate spin lifetimes (), determining how…
