Radiation Effects on Quartz Crystals and Oscillators, and Growth of Doped Quartz Crystals.
Abstract
Quartz crystals containing V(5+), Ga(3+), Mg(2+), Ge(4+) and Zn(2+) were grown. Kinetics of growth, segregation of the impurities and mechanical Q values of the crystals were investigated. Electron probe analysis has revealed in the grown crystals circular defects, some 2 - 15 microns in diameter. All investigated impurities were found to concentrate preferentially in these defects. Preliminary results have shown comparatively higher Q-values in Zn(2+) containing crystals. Radiation effects were investigated in various natural and synthetic resonators, before and after sweeping-in various monovalent ions. Thermoluminescence and thermally stimulated currents in the irradiated crystals were examined and a possible correlation between these properties and the piezoelectric properties was indicated.
