The objective of this study is to develop the analytical models for the dynamics of ZnO nanowires, nanobelts and nanosheets. We will study both the nonlinear single mode and the dual mode responses of these nanostructures subject to the electric field. These investigations will establish the link between the single crystal structure of ZnO and the nonlinear dynamics behavior of the nanostructures in nanowires, nanosheets and nanobelts. The study will lead to an exploration at a later stage of a series of different nanostructure oxides in different molecular structures for their behaviors in higher complexities, such as the coupled modal responses and chaotic synchronization.
Intellectual merit: The outcome of this research will push forward the sensor development in biochemistry and bioengineering, as well as for high precision instrumentation and field effect transistors, among others. Oxide-based nanostructures exist mostly in single crystal molecular structures. By a controlled growth mechanism, single-crystal semiconducting oxides in various forms of morphology have been synthesized, i.e. in the forms of nanowires, nanobelts, nanosheets and nanodiskettes as well as of nanorods. The diverse properties of the oxides show promise as future sensors in the areas of high precision scanning probes, gas sensors, and drug delivery carriers, as well as piezoelectric sensors and actuators.
We will focus on the nonlinear dynamics of the single crystal nanowire, nanobelt and nanosheet subject to an electric field. A series of Nonlinear Dynamics models will establish the quantified relations between the nanostructures and their dynamic behaviors under the applied field. These analytical models for ZnO-based nanostructures will be used for sensor development and characterization.
