Quasi-2D material based heterostructure devices and its applications

The structure and versatile interfacial properties of heterostructures of two-dimensional (2D) materials have drawn a lot of attention. The fundamental curiosity and efficient possibilities encourage the fabrication of 2D materials. 2D materials offer a variety of key elements with distinct optical, electrical, and optoelectronic characteristics. Recently, topological insulators became fascinating for the future of spintronics due to strongspin-orbit coupling and dissipation-less counter-propagating conduction channels in the surface state. When topological traits and magnetic order come together, they may result in new quantum states, leading to the quantum anomalous Hall effect. Here, an overview of 2D fabrication techniques, device applications, magnetic—topological coupling and interfacial effects in heterostructures is discussed, offering a flexible platform for engineering magnetic and topological properties, additionally providing perspectives on emerging research opportunities.
