|Title:||Velocity angular dispersion of surface and bulk modes in LiTaO3 at hypersonic frequencies||Authors:||Kuok, M.H.
|Issue Date:||29-Jan-2001||Citation:||Kuok, M.H., Ng, S.C., Zhang, V.L., Fan, H.J. (2001-01-29). Velocity angular dispersion of surface and bulk modes in LiTaO3 at hypersonic frequencies. Applied Physics Letters 78 (5) : 607-609. ScholarBank@NUS Repository. https://doi.org/10.1063/1.1343469||Abstract:||The existence of two surface acoustic waves, the Rayleigh wave and the second leaky wave, on X-cut LiTaO3 has been detected using Brillouin scattering. Evidence of dispersion between ultrasonic and hypersonic velocities was found for both surface and bulk acoustic waves. Elastic constant values were determined from a simultaneous least-squares fit of the angular dispersion data for the longitudinal and the two transverse hulk acoustic modes. © 2001 American Institute of Physics.||Source Title:||Applied Physics Letters||URI:||http://scholarbank.nus.edu.sg/handle/10635/98550||ISSN:||00036951||DOI:||10.1063/1.1343469|
