Abstract: Abstract Lead-free piezoelectric one-dimensional (1D) nanostructures have exhibited great potential in building biocompatible micro/nano-energy harvesters and self-powered smart sensors. However, their low piezoelectric coefficient still remains as the biggest obstacle for practical applications. In this… read more here.

Abstract: ABSTRACT Yb2O3 doped (K,Na)NbO3-0.5% Er2O3 (KNNEr) ceramics with the composition around the morphotropic phase boundary was synthesized by microwave sintering. KNN co-doped Yb2O3/Er2O3 ceramics exhibited enhanced ferroelectric, piezoelectric properties owing to the donor doping effect.… read more here.
