“…In the last case, if taking a given point close to room temperature, the quality parameter QÁf with the frequency variation must change as a linearly proportional function in a manner of QÁf~f, i.e., the quality factor must not depend on the frequency in that approximation. That result has earlier been proven for operational frequencies up to 20 GHz at room temperature [7]. Also, this fact is of great practical importance, as it allows realizing acoustoelectronic devices on diamond substrates at hypersonic frequencies with an acceptable level of acoustic attenuation.…”

“…Earlier, we have obtained by means of HBAR based on PLS involved the single-crystalline diamond substrate and AlN thin-film piezoelectric transducer that such assumption has been quite fulfilled for operational frequencies up to 20 GHz at room temperature (Ref. [7]). Also, this fact is of great practical importance, as it allows realizing acoustoelectronic devices on diamond substrates at hypersonic frequencies with an acceptable level of acoustic attenuation.…”

“…The amplitude was enhanced by 68.6%, whereas −6 dB bandwidth was enhanced from 30.2% to 58.3%. Such acoustic impedance-matching techniques can be further developed to suit modern composite acoustic devices such as High-tone Bulk Acoustic Resonators (HBAR) and Solid Mounted Resonator (SMR) operating at microwave operational frequencies (20 GHz) [318][319][320][321]. These devices of thin film piezoelectric materials have interesting frequency response characteristics concerned with the acoustical performance and are of great importance as sensors.…”

“…Hence, owing to HBAR's high quality factor in the microwave band, one can get increasing sensitivity taking into account the high operational frequency which will sufficiently exceed that in SAW-or FBAR-based sensors. However, such an opportunity can only be realized if the substrate's material possesses low acoustic attenuation in the microwave frequency band, e.g., diamond [16]. Here, diamond's excellent acoustic properties were investigated in the microwave band up to 20 GHz.…”
