Ferroelectric single crystals with tetragonal compositions Pb(Zn13/Nb23/)O3-xPbTiO3 (PZNT) and high TC (1-x)BiScCo3-xPbTiO3 (BSPT) were grown by Flux technique, respectively. Dielectric and piezoelectric characterization revealed high thickness coupling coefficients. (kt > 60 %) and relatively low dielectric permittivities (εs < 300) qualifying them as candidates for high frequency (> 20 MHZ) single element transducers. Modeling based on the KLM equivalent circuit was performed resulting in projected bandwidth > 60 % for BSPT and > 70 % for PZNT and therefore high sensitivity. Single element transducers were fabricated with suitable matching and backing layers. For a PZNT transducer with a 35 MHz center frequency, a bandwidth of ∼ 80 % was realized.
