We are looking for a Postdoctoral Research Associate to focus on the synthesis and heterogeneity of two-dimensional (2D) materials. As a postdoc, you will support in-house science projects at the Center for Nanophase Materials Science (CNMS) that focus on how heterogeneity in 2D materials and their architectures can be understood and controlled through different synthesis and processing strategies for tailored functionality. This position resides in the Functional Hybrid Nanomaterials Group within the CNMS, Physical Sciences Directorate (PSD), at Oak Ridge National Laboratory (ORNL). As a core team member, you will help us develop and apply techniques to understand how to control the growth or assembly of 2D materials and assess their heterogeneity and functional properties. You will work primarily within the Functional Hybrid Nanomaterials Group using established physical vapor deposition and processing facilities (e.g., PLD, CVD, stamping, exfoliation, etc.) and characterization tools (optical spectroscopy, AFM, electronic transport, etc.), but will also collaborate with a diverse team of experimentalists and theorists at the CNMS to develop novel concepts that take advantage of our experts in nanofabrication, in situ electron microscopy, chemical functionalization, and scanning probe microscopy to reveal the link between the heterogeneity and properties of the 2D materials. OVERVIEW: This position provides an excellent opportunity to learn and perform ground breaking research in the synthesis and processing, characterization, and functionality of heterogeneous 2D materials within the stimulating, multidisciplinary environment at the CNMS. You will join research teams and carry out research to understand how heterogeneity, driven by synthesis and assembly techniques (e.g., PLD, CVD, stamping, exfoliation, nanofabrication, etc.), determines the functionality (e.g., electronic, spintronic, catalytic, etc.) of the materials that crosscut theme activities at the CNMS, with the principal goal of high-quality and high-impact scientific publications. As a national user facility, the CNMS supports a multidisciplinary and dynamic research environment to understand nanoscale materials and phenomena, and offers a diverse spectrum of nanoscience research activities including a nanofabrication facility; laboratory-based research on macromolecular materials, catalysts, functional nanomaterials, and magnetism and transport; characterization with electron microscopes, scanning probes, and x-ray diffraction and scattering, and laser spectroscopy.
IN THIS POSITION YOU WILL: Work as part of a dynamic team conducting CNMS in-house research that advances our understanding of nanomaterials while also leading to the development of capabilities that will eventually become available to the CNMS user community Perform synthesis and assembly of atomically-thin two-dimensional materials by techniques like PLD, CVD, stamping, exfoliation, nanofabrication, etc. Perform characterization of 2D materials and their architectures by a variety of techniques (AFM, SEM, Raman and other laser spectroscopic techniques such as PL, absorption, PL lifetime studies). Prepare 2D materials using lithographic clean-room techniques and perform electronic transport measurements. Work across the Heterogeneity theme and other themes at the CNMS to prepare samples for the highly specialized, in situ electron microscopy, scanning probe, and other unique facilities designed to characterize the structure and properties of these materials Help to establish new facilities and user capabilities at the CNMS, and collaborate with users for additional publications Present research and publish scientific results in peer-reviewed journals in a timely fashion Ensure compliance with environment, safety, health, and quality program requirements. Maintain strong dedication to the implementation and perpetuation of values and ethics
