Theoretical Analysis of Acoustic Attenuation and Nonlinearity in Barium Monochalcogenides in B2 Phase
Barium chalcogenides Ultrasonic attenuation Phonon-phonon interaction
2010/4/9
Temperature dependence of ultrasonic attenuation due to phonon-phonon interaction and thermo-elastic loss have been studied in (CsCl-type) barium monochalcogenides (BaX, X= S, Se, Te), in the temperat...
