These will lay the groundwork for designing a new platform for realizing quantum devices. We aim to achieve quantitative measurements of interfacial interaction at the angstrom scale and unveil many details regarding local interactions between these 2D monolayers. Therein, the combination of high spatial, energy, and chemical resolutions provided by state-of-the-art methods is highly desired to reveal unprecedented details of the quantum behaviors involving charge, spin, valley, lattice, and other degrees of freedom. The discovery of new quantum materials and the understanding of quantum phenomena benefit from the improvements in experimental techniques. The study of quantum science involves diverse fields including physics, chemistry, and materials science. Investigating interface of 2D materials and heterostructures at the atomic scale. We aim to characterize active surface sites with single chemical bond sensitivity, which can correlate the local structure and function of catalysts. The development of next-generation catalysts relies on defining and understanding the sites on the catalyst surface which are most responsible for their useful behavior. Catalysis involves chemical transformations that must be understood at the atomic scale since catalytic reactions present an intricate process of chemical bond-breaking and bond-forming steps on only a few isolated sites. They feature a variety of surface defects and a great deal of crystallographic inhomogeneity. The catalysts and supports span a range of shapes and sizes. With specifically chosen molecular units, the functionality of the overall nanostructure can be finely manipulated, which allows us to design and perfect atom- and energy-efficient fabrication of revolutionary new materials with tailored properties.ĭetermining the mechanism of chemical bond formation under various local environments We directly probe these nanocontacts using scanning tunneling microscopy (STM) and tip-enhanced Raman spectroscopy (TERS). The ordering of molecules on a substrate is governed by the interplay of intermolecular and interfacial interactions. To achieve this goal, we use molecular self-assembly, a powerful bottom-up approach for fabricating molecular nanostructures. The design and fabrication of well-defined molecular nanostructures at solid surfaces is highly attractive for a variety of applications ranging from molecular optics and electronics to chemical sensors.
