Ion-beam-induced in-plane a-axis oriented (0001) AlN and ScAlN thin film BAW resonators

High-Q RF bulk acoustic wave filters are still required for mobile communication applications. However, the in-plane orientation of commercial AlN films is random, despite their excellent out-of-plane c-axis orientation. We proposed combining two different orientation control techniques: self-textur...
