Over the past two decades, two-dimensional (2D) van der Waals (vdW) materials have emerged as an exciting platform for materials science research owing to their wide array of fascinating properties and naturally vertical integrability. Beyond the many unique properties found within the growing families of 2D materials in isolation, exciting new opportunities have arisen upon integrating two or more of these layered materials into heterostructures. Because layers are coupled by van der Waals interactions rather than chemical bonding, these manually-assembled heterostructures can feature rich chemical compositions, flexible stacking orders, designable layer numbers, and gate-controlled physical properties. In the past few years, the discovery of flat electronic bands with hidden quantum geometry has sparked a new era for this field. Moiré superlattice engineering provides one means of generating such flat bands, giving rise to a broad spectrum of interesting electronic phases such as those featuring strong electron correlations and nontrivial band topology. Prime examples are gate-tunable magnetism, superconductivity, Wigner crystallization, nematicity, and (integer and fractional) quantum anomalous Hall effects. Similar phases can also be found in rare crystalline forms of 2D materials even in the absence of any moiré effect. Additional opportunities enabled by combining 2D materials with 3D materials are also starting to be explored. This rapid progress underscores the rich potential for future scientific discoveries and the development of innovative engineering applications by integrating advances in material synthesis, device fabrication, property characterization, and theoretical modeling. Our symposium will highlight the recent developments in 2D material heterostructures of all types, including their synthesis, fabrication, characterization, modeling, and novel devices. Specific focus areas will be on the forefronts of 2D materials discovery, the fabrication of novel vdW heterostructures, understanding intrinsic and extrinsic properties of these materials, and advancing device applications. The symposium will attract a worldwide group of researchers from a variety of scientific backgrounds, all working at the frontiers of these fields. We aim to broadly cover the exciting recent progress in these areas and identify promising future directions for the field.
