2D quantum heterostructures investigated by the QSPLEEM at the Molecular Foundry

ORAL

Abstract

Assembly of atomically thin 2D materials have enabled emerging possibility of precise control of the symmetry and quantum properties of matter. The interfaces of the 2D heterostructures present a plethora of measurables that are important for both fundamental understanding of matter and applications in quantum information science (QIS). At the Molecular Foundry, we used the newly commissioned, one-of-its-kind, the quantum spin-polarized microscope (QSPLEEM), in conjunction with scanning probe microscopes (SPM), and a home-built scanning confocal Raman/PL spectro-microscope, to investigate the heterogeneity, electronic, magnetic and opto-electronic properties of 2D heterostructures. We showcase the capability of image and manipulation of 2D quantum heterostructures with multiple degrees of freedom, including but not limited to: charge, spin, symmetry and light-matter interaction.
