Employer: Oak Ridge National Laboratory
Location: Oak Ridge, TN, United States
Posted: Jul 26, 2013
Expires: Aug 26, 2013
- Description
- PURPOSE:
Under general supervision, the incumbent will focus on the growth of composite thin films of ferroelectric oxides and magnetic intermetallic materials by Sputtering and Pulsed Laser Deposition. The magnetic, ferroelectric, and electronic properties of these composite materials will then be examined to determine the coupling between magnetic and ferroelectric properties. This position resides in the Functional Hybrid Nanostructures Group in the Center for Nanophase Materials Sciences (CNMS) Division, Physical Sciences Directorate (PSD) at Oak Ridge National Laboratory (ORNL).OVERVIEW:
This position will strengthen ORNL’s ongoing efforts in the area of multiferroic thin films and in particular advance new research on interfaces between intermetallic alloys and complex oxides, in direct collaboration with M.D. Biegalski, H.M. Christen, and R. Ramesh. The work will involve the growth of transition metal oxides and metallic thin films and heterostructures by pulsed laser deposition (PLD) and RF sputtering and the study of magnetoelectric coupling at their interfaces. The incumbent should be willing and able to take full advantage of well-equipped laboratories for the characterization of structure, magnetism, ferroelectricity, and electronic transport. A desire to collaborate with researchers in scanning probe and electron microscopies, neutron scattering, as well as theory and modeling, is expected.MAJOR DUTIES/RESPONSIBILITIES:
• Perform fundamental studies and optimization of growth processes in oxide and metallic thin films using pulsed laser deposition and sputtering techniques.
• Conduct research that focuses on understanding and optimizing coupling at interfaces in magneto-electric and multiferroic heterostructures.
• Use multiple techniques for the analysis of atomic structure including x-ray diffraction, neutron scattering, atomic force microscopy, as well as reflection high energy electron diffraction; and take advantage of the opportunity to interact with transmission electron microscopy researchers.
• Work with other CNMS postdocs and staff who are involved in the synthesis, characterization, and device applications of thin films synthesized at the CNMS.
• Responsible for presenting and reporting research results and publishing scientific results in peer-reviewed journals in a timely manner.
• Ensure compliance with environment, safety, health and quality program requirements
• Maintain strong commitment to the implementation and perpetuation of values and ethics.QUALIFICATIONS REQUIRED:
A PhD in Physics, Chemistry or Materials Science or a related discipline within Physical Sciences is required. The incumbent must have completed all degree requirements before starting their appointment and be within five years of receiving their Doctorate. A background in thin film growth of relevant material systems and familiarity with physical deposition process is required. The ability to conduct creative, independent research and possession of a strong background in electrical and magnetic characterization of materials are keys to success. The incumbent must be capable of innovative, independent research in this area. Excellent interpersonal skills and oral and written communication skills are mandatory. The ability to work collaboratively in a team environment and interact effectively with a broad range of colleagues is required. The ability to communicate in English to an international scientific audience and a strong record of productive and creative research demonstrated by publications in peer-reviewed journals are required. Working knowledge of Microsoft Office (which includes Word, PowerPoint, and Excel) is required. Must be able to set priorities, multi-task and adapt to ever changing needs with the proven ability to function well in a fast-paced environment.QUALIFICATIONS DESIRED:
A strong background in thin film growth with RHEED as well as expertise in materials characterization using four-circle x-ray diffraction, SQUID magnetometry, AFM, and electrical/magnetotransport characterization (using a PPMS) are preferred.This position is for one year with the option to renew term annually for a maximum of three years.
