  Project 1. In Situ TEM Imaging and Mechanistic Understanding of Crystallization and Reconfiguration in Nanocrystal Superlattices• Synthesized highly monodisperse polymer-grafted gold nanocrystals and imaged their self-assembly pathways into superlattices using in situ liquid cell transmission electron microscopy (LCTEM)• Analyzed the microscopic kinetics of crystallization in diverse LCTEM systems using machine learning-based image segmentation and custom-written MATLAB scripts• Discovered an unexpected multistep crystallization pathway at the nanoscale and opened new opportunities for elucidating complex mechanisms of nanoparticle self-assembly in nonaqueous solution.Project 2. Synthesis of Infrared Plasmonic Metal Oxide Semiconductor Nanocrystals for Optical and Electronic Applications• Developed a new synthesis methodology of infrared plasmonic metal oxide semiconductor nanocrystals with tunable optical and electronic properties• Characterized the structures and properties of the synthesized metal oxide semiconductor nanocrystals using different material characterization tools (X-ray and electron-beam techniques, etc.)• Studied localized surface plasmon resonances (LSPRs) spectra using custom-written MATLAB codes and simulated the spectra and near-field enhancement maps using FDTD method• Fabricated semiconductor nanoparticle thin film via spin coating, layer-by-layer deposition and thermal annealing; tested thickness, surface morphologies, atomic composition, and sheet resistance by AFM, SEM, SEM-EDX, and four-point probe measurement; milled the nanoparticle thin film using FIB to check film cross-section• Deepened the understanding of the relationship between local structure and properties of metal oxide nanocrystals and paved the way for systematic design and engineering of complex metal oxide NCs with emerging plasmonic, electronic, and magnetic properties Show less
