Arthur P Baddorf
Senior Research Staff, Scanning Tunneling Microscopy Group
Art Baddorf has studied materials for over 30 years at Oak Ridge National Laboratory (ORNL). He is currently a Senior Research Scientist in the Scanning Tunneling Microscopy Group at the Center for Nanophase Materials Sciences (CNMS), a Department of Energy Nanoscale Science Research Center. The 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 complex surfaces and interfaces, electron scattering and excitations, and energy flow at the nanoscale. Recent projects include analysis of carbon nanospikes, pulsed laser synthesis of oxide thin films, ferroelectric properties of surfaces and ultrathin films, molecular self-assembly in 2D, and electronic transport in quantum materials. Art serves on a number of ORNL and national advisory boards and has published over 150 journal articles.
