Innovative Techniques for Studying New Materials and New Developments in Solid State Physics

Abstract

The goals of this project involve the use of innovative acoustic techniques to study new materials and new developments in solid state physics, such as effects in mesoscopic electronic systems. Major accomplishments include (a) the publication of a number of major papers, (b) the determination of the anisotropy of an aluminum alloy quasicrystal, (c) the completion of ultrasound measurements on ceramic beads with varying heat treatment, (d) preparation of a diamond substitute material, TiB 2, for determination of the elastic constants, (e) the development of a new transduction method for measuring optical absorption in highly transparent materials, (f) the determination of the effects of nonlinearity on Anderson localization, and (g) the use of an acoustic analog to explain the discrepancy between theory and experiment for normal electron persistent currents in a mesoscopic system.
