  1. Ultrahigh piezoelectricity in Pb-free crystalsDwight D, Viehland, Virginia Polytechnic Institute and State University, DMR 0806592 Recently, ultrahigh piezoelectricity was realized in Mn-doped NBT-5.6%BT Pb-free crystals (Fig.a), which were grown by TSSG method. The induced charge per longitudinal unit force (a quantity known as d33) of this new lead-free crystal surpassed most successful piezoelectric ceramics of the PZT4 type (see Table I). Our results have been published in a recent issue of Applied Physics Letters 95 (2009) 102904. Mn:NBT-5.6%BT single crystal d33483pC/N Polarization hysteresis loop Table I.
