In this talk, I will briefly introduce the recent research results of piezoelectric nanostructures. Scientifically, the quantum size effect gives rise to significant modifications of the Curie temperature, domain structure, and piezoelectric constant. Technically, piezoelectricity, as well as ferroelectricity, provides the useful building blocks for nano-actuators, ultra-high-density memories, energy-harvesting devices, and hydrogen-generating devices. Due to the recent significant progress in synthesis techniques, the area of piezoelectric nanostructures has become one of the hottest research fields in condensed matter physics.
