Atomic Scale Synthesis and Characterization of Organic-Inorganic Hybrid Molecular Structures on Graphene and Boron Nitride
Abstract
Title: Atomic Scale Synthesis and Characterization of Organic-Inorganic Hybrid Molecular Structures on Graphene and Boron NitrideA major obstacle impeding the realization of novel device functionalities lies in the controlled synthesis of materials at the atomic scale and the ability to carry out measurements of their properties at such length scale. Using the bottom-up approach, devices consisting of a countable number of atoms with designed composition and structure can be fabricated and with functionalities that follow quantum principles. This project seeks to fabricate hybrid organicinorganicnanoscale molecular structures from single atoms and molecules to covalently linked assemblies on two-dimensional graphene and boron nitride islands. In addition, by co-exposure of the surface to magnetic atoms and cyclic organic molecules, combined with temperature control, new hybrid organic-inorganic sandwiched molecules can be realized that are challenging to synthesize chemically in flasks. Understanding the magnetic, optical, vibrational, andelectronic properties of these hybrid molecular structures with the scanning tunneling microscope would provide the basic knowledge to assess their potential as the basic units for quantum sensing, devices, and information processing. An important challenge lies in the control of coherence of the vibration and spin states. In addition, the combination of a femtosecond laserwith the scanning tunneling microscope enables the probing of the effects of graphene and boron nitride on the interactions of light with the supported hybrid molecular structures in the time domain. Along with these project outcomes, new understanding into spin interactions in covalently linked two dimensional ordered assemblies of magnetic molecules is anticipated. The basic knowledge of chemical control of hybrid organic-inorganic molecules and their integrationinto systems would advance quantum science and technology that would impact Department of Defense capabilities.
