| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Mobile communication device requires high power operation. Nonlinear signals such as second harmonic (H2) generation (SHG) is not negligible for recent BAW filter applications. It is well known that the change of resonant frequency during DC bias voltage application is related to SHG. Also, the DC voltage application induces the change of lattice strains and elastic stiffness in piezoelectric crystals. In this study, we estimated the change of resonant frequency and inverse dielectric constants during DC bias voltage application in the AlN and ScAlN SMR. Moreover, we investigated the change of lattice strain under DC bias using XRD. | |
