Mission Statement

SHINES EFRC will explore the interplay of spin, charge, and heat to control the transport of spin and energy to achieve significantly higher energy efficiencies in nanoscale electronic devices. The objectives for the SHINES center include (1) better understanding of and significant improvement in pure spin current effects in nanoscale electronic devices, including magnonic switching, spin-torque oscillations, spin-orbit torques, and spin Seebeck effect through novel materials and heterostructures; (2) engineering of acoustic phonon and magnon transport in nano-structured materials via controlling their dispersions and interactions; and (3) exploration of spin-orbit coupling for low energy effects and spin superconducting condensate for dissipationless spin and energy transport.

Grand Challenge

"How do we control material processes at the level of electrons?" identified by the "Basic Research Needs" workshop, New Science for a Secure and Sustainable Energy Future, including the recurring theme of "control of photon, electron, spin, phonon, and ion transport in material" and opportunities for "controlling matter and energy at the electronic level."

The research is organized into three interactive themes of (1) Pure Spin Currents in Metals and Insulators; (2) Phonon/Magnon Transport and Phonon/Magnon Engineering in Nanostructured Materials; and (3) Spin-Orbit Coupling Heterostructures and Highly Correlated Spin Materials. With intensive collaboration with other themes, each theme engages in a spectrum of activities including materials synthesis (e.g. high-quality ultrathin magnetic insulator films, nanostructured composites, few atomic layer van der Waals (vdW) materials, and heterostructures) and characterization (e.g. x-ray-based spectroscopy at DOE labs), device nanofabrication, electrical/thermal transport and light scattering measurements (e.g. Raman and Brillouin light scattering), as well as theory, simulations, and modeling.
