Description of Institution

The Neutron Sciences Directorate (NScD) at Oak Ridge National Laboratory (ORNL) operates the High Flux Isotope Reactor (HFIR), the United States’ highest flux reactor based neutron source, and the Spallation Neutron Source (SNS), the world’s most intense pulsed accelerator based neutron source. Together these facilities operate 30 instruments for neutron scattering research, each year carrying out in excess of 1,000 experiments in the physical, chemical, materials, biological and medical sciences for more than 3,000 visiting scientists. HFIR also provides unique facilities for isotope production and neutron irradiation. To learn more about Neutron Sciences at ORNL go to: http://neutrons.ornl.gov. The Computing and Computational Sciences Directorate (CCSD) in ORNL is home to some of the world’s most advanced supercomputing infrastructures (For more: https://www.olcf.ornl.gov).

Job description

Purpose:

The Quantum Condensed Matter Division (QCMD) https://neutrons.ornl.gov/qcmd in the Neutron Sciences Division (NScD) at ORNL operates 13 instruments for elastic and inelastic neutron scattering studies of materials including the Magnetism Reflectometer. Instruments are located at both HFIR and SNS. QCMD conducts research on materials with emergent properties that are manifestly quantum in origin. Some examples of current interest include superconductivity, toplogical insulators, low dimensional magnetism, nanocomposite and mesoscale magnetic materials.

Quantum Condensed Matter Division (QCMD) has an immediate opening for an outstanding candidate for a postdoctoral position with a strong background in Physics and with skills in computer/computational science to be involved in development of highly optimized software tools for the analysis and modeling of Grazing Incidence Neutron Scattering at the Spallation Neutron Source of the interface driven properties of complex heterostructures.

This position will be located in in the Thin Films and Nanostructures Group of the Quantum Condensed Matter Division (TFN QCMD) and benefits from strong interactions with the Center for Nanophase Materials Sciences (CNMS) and Computing and Computational Sciences Directorate (CCSD) at ORNL and will comprise a diverse spectrum of nanoscience activities. Neutron Reflectometry at the SNS is used to investigate thin film heterostructures which exhibit unusual physical properties that are important for science and technology and represent recent key innovations. The availability of high performance polarized and unpolarized neutron reflectometry is vital for understanding properties in the systems that include: (i) innovative new generation of heterostructures based on integrating topological insulators with conventional materials to induce ferromagnetic interactions with symmetry breaking at the interface ; (ii) multifunctional oxide heterostructures with unusual physical properties important from both the fundamental and device application viewpoints; (iii) spintronic devices using magnetic tunnel junction with a perpendicular magnetic anisotropy, (iv) tunnel barriers in hybrid organic/metallic spin-valve structures; and (v) structural characteristics of active layers in organic photovoltaic devices.

The successful candidate will conduct scientific research using exceptional experimental capability and will be engaged in development of highly optimized software tools for the analysis and modeling of Grazing Incidence Neutron Scattering (GINS) at the Spallation Neutron Source of the interface driven properties of complex heterostructures. Full training will be given in all aspects of neutron reflectometry including beamline operation, data acquisition, processing and modeling.

Major Duties/Responsibilities:

  • Conduct research on a mutually agreed topic in magnetic thin films and nano-structures using the Magnetism Reflectometer and other instruments as appropriate and to publish scientific papers resulting from this research and present results at appropriate national and international meetings.
  • The successful candidate will be part of the Thin Films and Nanostructures group in the Quantum Condensed Matter Division at ORNL and will be expected to take part in all group activities, which include seminars and monthly meetings.
  • Ensure compliance with environment, safety, health and quality program requirements.
  • Maintain strong commitment to the implementation and perpetuation of values and ethics.
  • Physical requirements for this job include the use of hand and eye protection gear, kneeling, sitting for extended periods of time, extensive work at chemical laboratories, and possible exposure to ionizing radiation normally associated with operation of neutron scattering instruments for scientific research.

Work Directions and Interfaces:
Reports to Valeria Lauter. Will interface with the MR instrument team, Software scientists.
