Electro-mechanical tuning of high-q bulk acoustic phonon modes at cryogenic temperatures

HIGHLIGHTS

• who: William Campbell et al. from the Department University of Crawley, Washington, Australia have published the research work: Electro-mechanical tuning of high-Q bulk acoustic phonon modes at cryogenic temperatures, in the Journal: (JOURNAL)
• what: The authors investigate the electromechanical properties of quartz bulk acoustic wave resonators at extreme cryogenic temperatures. By applying a DC bias voltage, the authors demonstrate broad frequency tuning of high-Q phonon modes in a quartz bulk acoustic wave cavity at cryogenic temperatures of 4 K and 20 mK. The authors demonstrate highly stable electromechanical tuning of an acoustic . . .
