Acoustic Studies of New Materials: Quasicrystals, Low-Loss Glasses, and High Tc Superconductors
Abstract
The goals of this project involve the development and application of new techniques in acoustics. The goals are: (a) to study the properties of single crystal high temperature superconductor oxide materials with ultrasonic measurements; (b) to study the properties of quasicrystals using ultrasound and acoustic analog systems; and (c) to develop and apply a new resonant photo- acoustic technique to measure optical absorption in very low-loss glasses and crystals. Major accomplishments include the development of a new method of ultrasound elastic constants of very small samples (a few hundred microns in size), and the development and test of a new technique for measuring optical absorption with more than an order of magnitude improvement in sensitivity over existing methods.
