2D materials for intelligent devices

Neuromorphic intelligent hardware technologies have undergone rapid advancement during the past decade, with the goal of building intelligent devices and systems capable of overcoming challenges associated with conventional hardware. Realization of neuromorphic intelligent hardware depends on major advances in materials science, condensed matter physics, device physics and engineering. As a revolutionary discovery, two-dimensional (2D) materials with atomically-thin thickness and exceptionally high tunability introduce a new physical paradigm and show great promise in the development of intelligent devices. Here, we give prominence to three categories of tunable properties (i.e., charge carrier, band structure, lattice structure) that are inherent for 2D materials and review their superiorities in constructing intelligent devices particularly in electronics and optoelectronics. Furthermore, we provide insight into how the unique physical mechanisms emerging in 2D materials offer a fertile ground for the design of diverse intelligence devices.
