Symposium NM01-Moire Superlattices in 2D Materials

Superimposing two periodic lattices with different lattice constants or a relative twist generates a moiré superlattice with longer periodicity. Superlattices are a powerful approach to create materials with novel and highly tunable mechanical, optical and electrical properties. In particular, moiré superlattices composed of twisted two-dimensional (2D) material bilayers or heterostructures have generated excitement as they feature flat bands, strongly correlated electron states, and novel topologies leading to Mott insulators, unconventional superconductivity, anomalous quantum Hall effect, moiré confined excitons, microscale superlubricity, etc. This symposium will bring together a group of leading experts to address the diverse physics, chemistry and materials challenges and opportunities, including the synthesis of the moiré superlattices, interfacial mechanics, superlattice reconstructions, novel electronic phases, excitonic and optical states, multiscale modeling to accurately predict structure and properties, and local probes for measuring electronic states at the moiré scale. The symposium will not only give an overview of the current state of this dynamic research field, but also highlight future avenues to advance moiré materials for applications in electronics, mechanically reconfigurable materials, transducers, and quantum information.

Topics will include:

  • Experiment and theory of structures, properties and applications of moiré superlattices
  • Synthesis and manufacturing strategies to generate moiré superlattices
  • Interfacial structure and reconstruction mechanics of the superlattice at van der Waals interfaces
  • Moiré superlattices in non-van der Waals materials
  • Manipulation of moiré superlattices via lattice alignment, twist, and strain
  • Optical spectroscopy and transport measurements probing superlattice states
  • Imaging moiré superlattices using local probes such as scanning probe, tip-enhanced optical probe and electron microscopy, etc.
  • Multiscale theories for accurately predicting the structure and electronic properties of moiré superlattices, ranging from ab initio calculations, dislocation models, electronic continuum methods, many-body approaches
  • Optical, electronic, mechanical, and topological properties of moiré superlattices
  • Novel physics resulting from the emerging topologies and highly correlated electron states such as superconductivity, ferromagnetism, ferroelectricity, Mott insulators, interlayer and moiré exciton confinement and tuning
  • Twistronics, straintronics, spintronics and valleytronics applications of moiré superlattices
