Group Leader, Scanning Probe Microscopy

Bio

Art Baddorf has studied materials for over 30 years at Oak Ridge National Laboratory (ORNL). He is currently leader for the Scanning Probe Microscopy group at the Center for Nanophase Materials Sciences (CNMS), a Department of Energy Nanoscale Science Research Center. His group operates over 15 microscopes that use an extremely sharp tip to explore nanoscale objects and surfaces using either force (atomic force microscopy) or current (scanning tunneling microscopy). The techniques allow mapping of properties such as conductivity, polarization and ferroelectricity, magnetism, dielectric constant, thermal conductivity, and local density of electronic states at resolutions down to individual atoms. Art’s research interests focus on a fundamental understanding of the relationship between atomic structure and properties at oxide surfaces and interfaces, ferroelectric domain engineering, electron scattering and excitations, and energy flow at the nanoscale. Recent projects include pulsed laser synthesis of oxide thin films, ferroelectric properties of surfaces and ultrathin films, molecular self-assembly in 2D, and electronic transport in transition metal oxides. Art serves on a number of ORNL and national advisory boards and has published over 130 journal articles.

Projects

1. Atomic structure of oxide surfaces and interfaces
Understanding and control of the wide range of properties discovered in oxide thin films and interfaces depend critically on the exact atomic structure, which we explore using scanning tunneling and non-contact force microscopies.
2. Domain Engineering: Ferroelectrics
Extensions of Piezoresponse Force Microscopy are used to examine switching, domain growth, and domain control in thin film ferroelectrics.
3. Transport in non-metallic oxides
The transport of electrons in thin oxide films is mapped at nanometer length scales as a function of temperature, applied voltage, and internal polarization in ultra high vacuum as a tool to understand oxide behavior through injection, hopping, and vacancy motion.
4. Electron Scattering and Excitations
Experiments for an atomic level understanding of electronic properties and dynamics, including electron transport, excitations, spin correlations, and interactions.
5. Energy flow at the nanoscale
We seek a fundamental understanding of energy flow and dissipation at nanometer scales using band excitation techniques in atomic force microscopy (tip surface dissipation) and inelastic tunneling spectroscopy in scanning tunneling microscopy (electronic excitation).
