Description
This fellowship opportunity supports research at the Naval Research Laboratory (NRL) focused on understanding the spin dynamics involved in charge to spin conversion within topological insulators. Unlike traditional heavy metals where spin-dependent scattering dominates, topological insulators rely on band structure details, enabling ultrafast charge to spin conversion processes that are not yet well understood.
The research involves experimental observation of spin dynamics using both optical and electrical methods. A key goal is to integrate these ultrafast spin dynamics with antiferromagnetic materials to achieve switching of the Neel vector at near terahertz (THz) frequencies. This combined effort includes fabrication, characterization, and theoretical modeling to advance topological device technologies.
The scientific outcomes aim to enhance efficiency in next-generation low-power computing, information processing, on-chip THz communication, and in-logic memory devices.
