Abstract
Section titled āAbstractāUltra high frequency attenuation limits in synthetic IIa diamond single crystal were studied. The investigations were provided by High-overtone Bulk Acoustic Resonator āAl/AlN/Mo/(100) diamondā. It was shown, that the change of Akhiezerās attenuation regime to Landau-Rumer one takes place at f ā 1 GHz. The experimental results on the quality parameter showed QĆf ā 1.8Ā·10 <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>13</sup> Hz for Akhiezerās regime, and QĆf ā fĆ1.8Ā·10 <sup xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>4</sup> Hz for Landau-Rumer regime. As a consequence on a higher frequencies diamond single crystal has more preferred acoustic parameters including a lower acoustic attenuation in comparison with known acoustoelectronic materials.
