High-tone bulk acoustic resonators (HBARs) have been fabricated on four types of substrates: c-axis sapphire, AT-cut crystal quartz, fused silica, and โจ100โฉ single crystal silicon. Quality factors of the HBARs on the four substrates have been compared. Temperature effect on the Q and resonant freque
