Opportunity Description

Title of Research Opportunity: The Enhanced Efficiency of Thermoelectric Applications Utilizing Hetero-Nanostructures and Materials The research opportunity design and structure-property-function relationships of heteronanomaterials. Specifically, the opportunity seeks to study of emerging nanomaterials via growth, synthesis, characterization, and assembly with a focus on applications in thermoelectric (TE) power generation. The research seeks to investigate nanomaterials and van der Waals heterostructures made from them for enhanced thermal and electronic transport properties. The ultimate technology goal includes fabrication of efficient, low-cost, low-power thermoelectric generators and Peltier coolers for military and commercial applications. In conjunction with this goal, the research comprises of developing materials with high TE figure of merit (ZT) by preparing them in quantum well (nanostructured) super lattice (monolayer) as first described by Hicks and Dresselhaus [1]. Preliminary results show successful growth of nanostructure TE material (Bi2Te3) [2] as well as van der Waals thin film (graphene) for thermoelectric measurements (Seebeck, Resistivity, and Thermal conductivity). The research endeavor requires expertise in electron microscopy, surface probe microscopy, and spectroscopic techniques including; Scanning Probe Microscopy, Scanning and Tunneling Electron Microscopy, Laser Spectroscopy (Raman, IR), X-ray Diffraction.

About Us

Grooming future leaders in science and technology requires enhancing the skills, knowledge and experience of workers early in their careers. To that end, ORAU (Oak Ridge Associated Universities) assists in connecting the best and most diverse students, recent graduates, faculty and professionals with world-class fellowships, internships and jobs, whether in national laboratories, research institutions, federal government offices or private sector R&D departments.

ORAU works with agencies such as the U.S. Army Research Laboratory (ARL) Research Associateship Program (RAP) allow Postdoctoral Fellows, Journeyman Fellows (undergraduate and graduates students and recent graduates), Senior Researchers, and Summer Faculty engage in research initiatives of their own choice, that are compatible with the interests of the government and will potentially contribute to the general effort of the ARL. We work with the Environmental Protection Agency (EPA) to place recent graduates in full-time and part-time jobs in the Office of Research and Development at EPA under the National Student Services Contract. ORAU also works with Center for Medicare and Medicaid Innovation.

Research opportunities include, but are not limited to the following disciplines: Aerospace Engineering, Anthropology, Archeology, Biology, Biochemistry, Biological Engineering, Biomechanical Engineering, Biomedical Engineering, Chemical Engineering, Chemistry, Computer Science, Computer Engineering, Data Science, Electrical Engineering, Environmental Health Risk Assessment, Environmental Science, Entomology, Epidemiology, Ergonomics, Geology, Health Education Mechanical Engineering, Materials Science, Mathematics, Nanotechnology, Photonics, Physics, Public Health Economics, Public Health Policy, Toxicology, and more.
