Open Nanoacoustic Resonators Based on SrTiO${}_3$/YBa${}_2$Cu${}_3$O${}_{7-x}$ Superlattices

S. Sandeep, O. Colmegna, S. Carreira +4

We report the design and experimental demonstration of an open nanophononic cavity based on a hybrid oxide superlattice composed of SrTiO${}_3$ (STO) and YBa${}_2$Cu${}_3$O${}_{7-x}$ (YBCO…
