Data-mining for Rapid Analysis of Massive Materials Science Databases. Developing data-mining techniques to accelerate the discovery of advanced materials. These new data-mining techniques integrate solid state physics, lattice and symmetry analysis, and information theory. The data-mining techniques are run both offline and online during sample characterization to provide live guidance to the experimentalist and improve data collection. Techniques of interest include (but are not limited to) sparse kernel machines, latent variable analysis, and Bayesian analysis.
Discovery of structure phase diagram from composition spread data.
Theory of Field Induced Quantum Tunneling. Developed nist-equations for modeling field emission mechanisms of conductive ellipsoidal field emitters and established new metrics for comparing device performance. Performance metrics studied include the local field enhancement factor, the emission current density, the total emission current, the significant emission area, and the integrated field enhancement factor.
