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…
