Symposium's Technical Synopsis
Recent advances in nanofabrication technology and in the development of two‐dimensional (2D) crystals and heterostructures/interfaces of novel materials have enabled new possibilities to manipulate and conduct controlled studies of different quantum degrees of freedom (e.g., spin, valley, number of layers, symmetry, topology, etc.) in materials. For instance, 2D crystals of van der Waals (vdW) materials with honeycomb lattice structures, such as semimetallic graphene, insulating hexagonal boron nitride (h‐BN), and semiconducting transition metal dichalcogenides (TMDCs) that exhibit strong spin‐valley coupling, have simulated intense research efforts due to their rich physical properties and great promises for technological applications in nanoelectronics, spintronics, valleytronics and optoelectronics. The surface and edge states of strong spin‐orbit coupled topological insulators in proximity to either ferromagnetism or superconductivity can manifest the elusive topological magnetoelectric effect (TME) or Majorana fermion modes, which are not only of fundamental scientific importance but also promising for applications to spinorbitronics and quantum information technology. Monolayer interfaces of iron‐based superconductors (e.g., FeSe with a bulk superconducting transition temperature Tc ~ 8 K) with polar substrates (such as SrTiO3 or TiO2) have found an enhancement in the Tc value by nearly ten folds, suggesting the importance of quantum confinement and strong coupling to the occurrence of high‐Tc superconductivity. Nanoscale strain engineering of graphene by nanofabrication of meta‐structures can induce giant pseudo‐magnetic fields (up to ~ 104 Tesla local fields at nanoscales!) and strong valley polarization for novel valleytronics, whereas similar strain engineering of TMDCs can lead to controlled spatially varying bandgaps and optical luminescence for optoelectronics and optospintronics.
