Union between top-down and bottom-up assembly is inevitable when scaling down physical, chemical, and biological sensors and probes. Current sensor-probe-based technologies are firmly founded on top-down manufacturing, with limitations in cost of production, manufacturing methods, and material constraints. As an alternative to such limitations, contemporary synthesis techniques for one-dimensional nanostructures have been combined with established methods of micro-fabrication for the development of novel tools and techniques for nanotechnology. More specifically, this dissertation is a systematic study of the synthesis and characterization of ZnO nanostructures for piezoelectric applications. Within this study the following goals have been achieved: 1 rational design and control of a diversity of novel ZnO nanostructures, 2 improved understanding of polar-surface-dominated PSD phenomena among Wurtzite crystal structures, 3 confirmation of Taskers Rule via the synthesis, characterization, and modeling of polar-surface-dominated nanostructures, 4 measurement of the surface-charge density for real polar surfaces of ZnO, 5 confirmation of the electrostatic polar-charge model used to describe polar-surface-dominated phenomena, 6 dispersion of ZnO nanobelts onto the selective layers of surface acoustic wave SAW devices for gas sensing applications, 7 manipulation of ZnO nanostructures using an atomic force microscope AFM for the development of piezoelectric devices, 8 fabrication of bulk acoustic resonator BAR and film bulk acoustic resonator FBAR devices based on the integrity of individual ZnO belts, 9 electrical characterization of a ZnO belt BAR device, 10 prediction and confirmation of the electrical response from a BAR device using a one-dimensional Krimholt-Leedom-Matthaei KLM model, and 11 development of a finite element model FEM to accurately predict the electrical response from ZnO belt BAR and FBAR devices in 3D.
