Fabrication of Bulk Acoustic Wave Resonator with Multilayer Graphene Electrode

open access: yesphysica status solidi (b), Volume 262, Issue 12, December 2025.
Herein, multilayer graphene structures are grown on the silicon substrate for the fabrication of the bulk acoustic wave resonator device. The result reveals that both methods can be used to replace the Bragg reflector. Two bulk acoustic wave resonator (BAW) devices with multilayer graphene as bottom electrodes are fabricated using the chemical vapor ...
