Symposium NM06—Theory and Characterization of 2D Materials—Bridging Atomic Structure and Device Performance
This symposium will center around atomic structure engineering of 2D materials, with a focus on improvements in fundamental understanding and control of atomic-scale structure and how it can be used to tune functional properties on the device scale. Two-dimensional (2D) materials have emerged as a frontier of materials science: they are an ideal platform for fundamental science, represent the atomically-thin limits for miniaturizing electronic devices, and are ideal high-surface area materials for energy conversion and storage. For each of these applications, it is critical to develop an atomic-scale understanding and control of the structure of 2D materials - including their defects, alloys, strain, phase transformations, interfacial interactions both in 2D compounds as well as in monoelemental 2D crystals such as silicene, phosphorene, stanene, borophene, etc. In particular, atomic structure engineering can be used to tune the functional properties 2D materials across diverse areas, from controlling their surface chemistries for energy conversion/storage to controlling band structure through stacking faults, moiré structures and strain engineering.
Achieving the rational design of 2D materials and devices will require the development of new methods to synthesize, characterize, integrate, and model 2D materials. First, advanced characterization techniques are critical to measuring the structure of 2D materials with atomic precision and understanding variations in device performance. Meanwhile, theoretical and computational methods with different scales provide a fundamental backbone for connecting structure property relations. Finally, methods to scalably synthesize, interface, and integrate 2D materials as well to tune, pattern, and switch their properties are important for applying atomic-scale insights to improve device performance.
Quantum and topological properties of 2D materials are better suited for other symposium. MXene materials are also better suited for another symposium unless the focus is strictly on atomic structure (and related theory/characterization)
