Abstract
Experimental data are given showing the relationship of phase velocity, group velocity, and electromechanical coupling coefficient as a function of the normalized thickness h/λ for epitaxial (112̄0) ZnO on (011̄2) Al2O3. Delay time vs frequency for dispersive delay lines fabricated from epitaxial ZnO on Al2O3 is also given. Using these data, design criteria and assessments are made for the use of this composite material in fabrication of a dispersive delay-line device.This publication has 8 references indexed in Scilit:
