Abstract:

Particles, with physical size that is small enough, display properties which differ significantly from the bulk material due to both surface effects and quantum confinement effects. The characterization of electronic states that dictate their physical properties requires sensitive techniques to probe the metallicity of the surface and bulk of material. In addition, such sensitive technique should be able to probe both charge and spin degrees of freedom. NMR spectroscopy offers such sensitive probe of the electronic wave function, correlations, and dynamics. In this talk, I will discuss innovative resonance techniques that we have developed to study quantum size, surface, and spin-orbit coupling effects on the electronic properties of multimetallic, semimetalic, and magnetic nanoparticles (NPs), nanowires (NW), and their thin film structures. A particular focus of my talk will be on ITO (Indium Tin Oxide) based materials.
