Low-dimensional spintronics is a field of research focused on investigating the fundamental properties and behavior of electron spin, as well as its transport, manipulation, and detection, within materials and structures confined to reduced dimensions (typically zero, one, or two dimensions). This area explores how quantum confinement and dimensionality influence spin-related phenomena, leveraging the unique electronic and spin characteristics of low-dimensional systems such as 2D materials, nanowires, and quantum dots to develop novel spintronic functionalities and devices.
