Meso-size Effect from Self-assembled Carbon Structures and Their Device Applications
Abstract
Despite remarkable developments in the field of carbon nanomaterials, our ability to control and assemble these materials in the meso-size scale is still limited, a problem made more difficult by the lack of imaging tools with necessary resolution and speed. Therefore, there have been constant needs for the development of powerful new imaging and spectroscopy tools. Our main research achievement is the development of new imaging techniques for better mesoscale control of the growth and assembly of carbon nanotubes and graphene, one- and two-dimensional sp2 carbon nanostructures. More specifically, we have developed two new optical imaging techniques, widefield Raman imaging and DUV-Vis-IR hyperspectral imaging, for direct, high-throughput imaging of these 1D and 2D materials. Our new techniques have allowed the investigation of novel physical phenomena, including the angle dependent optical resonances in twisted bilayer graphene. These well-defined carbon nanostructures and their mesoscale assembly will lead to exciting new device applications in energy conversion and energy transfer.
