The interconversion between spin and charge degrees of freedom in van der Waals materials offers incredible potential for spintronic devices, especially with the emergence of materials possessing large spin-orbit coupling and layered ferromagnets. There is abundant room for progress in discovering and analyzing novel spin-charge interconversion phenomena, as well as exploring modifying properties through proximity effects. Recent advances in techniques for large-scale growth, device physics, and theoretical aspects have significantly contributed to the field.
The interconversion between spin and charge degrees of freedom offers incredible potential for spintronic devices, opening routes for spin injection, detection, and manipulation alternative to the use of ferromagnets. The understanding and control of such interconversion mechanisms, which rely on spin-orbit coupling, is therefore an exciting prospect. The emergence of van der Waals materials possessing large spin-orbit coupling (such as transition metal dichalcogenides or topological insulators) and/or recently discovered van der Waals layered ferromagnets further extends the possibility of spin-to-charge interconversion to ultrathin spintronic devices. Additionally, they offer abundant room for progress in discovering and analyzing novel spin-charge interconversion phenomena. Modifying the properties of van der Waals materials through proximity effects is an added degree of tunability also under exploration. This Perspective discusses the recent advances toward spin-to-charge interconversion in van der Waals materials. It highlights scientific developments which include techniques for large-scale growth, device physics, and theoretical aspects. (C) 2021 Author(s).
