Abstract in another language

Applications using BAW devices benefit from large intrinsic electromechanical coupling materials, e.g. Al 1-x Sc x N. This work reports BAW-SMRs using high piezoelectric Al 1-x Sc x N and investigates the relations between Sc content, crystal morphology and resonator RF performance. Finally, key requirements for high quality Al 1-x Sc x N thin-film growth are analyzed and discussed examplary for x = 20at.-%.
