Creator:: Shelton, Christopher T.
Abstract:: The lead-zirconate-titanate (PZT) solid solution system is currently the workhorse of piezoelectric-based microelectromechanical systems (MEMS) research. Among bulk materials it is known to be one of the strongest piezoelectrics, with extremely high piezoelectric coefficients and electro-mechanical coupling factors. Reproducing these exceptional qualities in thin film form, however, requires precise tuning...
Resource Type:: Masters Thesis
Full Text:: thin films were produced with conductivity around 600 µΩ-cm. These films are excellent

Creator:: Walenza-Slabe, Joel
Abstract:: Pb(Zr₀.₅₂Ti₀.₄₈)O₃ (PZT) thin films are of interest for their large dielectric permittivity, ferroelectric, and piezoelectric properties. The material has been widely studied for use in high frequency transducers, multi-layered capacitors, and ferroelectric random access memory. Copper foils are an inexpensive, flexible substrate with a low resistivity which makes them ideal...

Creator:: Dandeneau, Christopher S.
Abstract:: Since bulk p-CuO/n-ZnO heterocontacts were first proposed for gas detection, rapid development has taken place in improving the overall functionality of these structures. While bulk heterocontacts have been shown to exhibit desirable sensitivity and selectivity characteristics, these devices suffer from innate diffusion and ZnO/CuO connectivity drawbacks that limit their effective...

Full Text:: to product formation is lowered (Ec) when a catalyst is used

Creator:: Kremer, Matthew H.
Abstract:: Electrospinning and electrospray are both nano-scale material fabrication techniques, based on related phenomena of electrically charged fluid spray from a droplet of liquid. Material is dissolved in liquid, then a spray is generated by applying a high voltage, creating an electric field, between the fluid dispensing capillary and a grounded...
Resource Type:: Masters Thesis
Full Text:: electric field, Ec, required for electrospray generation and the relevant parameters[41]: 𝐸𝐶 = 2𝑉𝐶

Creator:: Grove, Kyle M.
Abstract:: Recent changes in legislation restricting lead content in waste streams produced during electronics manufacturing have inspired a strong push to develop alternative lead-free materials systems for piezoelectric applications. One lead-free piezoelectric material system, (100-X)Bi₀.₅Na₀.₅TiO₃-XBi₀.₅K₀.₅TiO₃ (BNKT), has shown promising properties in bulk research, however, difficulties have arisen in the development of...
Resource Type:: Masters Thesis
Full Text:: polarization begins to decrease as a negative electric field is applied until reaching the coercive field, Ec

Creator:: Le, Anthony H.
Abstract:: There are at least fifteen types of upper extremity tendon transfer procedures for combined peripheral nerve injuries that involve re-routing a single donor muscle to multiple recipient tendons. As a result, force and movement across finger joints become coupled, resulting in limited grasping abilities. Quantification and modeling of the donor...
Resource Type:: Masters Thesis
Full Text:: whole process is known as excitation-contraction (EC) coupling. Muscle relaxation occurs after EC

Creator:: Landau, Nicholas P.
Abstract:: The research presented herein represents an effort to combine the ultra-smooth surface of an amorphous metal thin ﬁlm (AMTF) with a solution-processed dielectric synthesized via prompt inorganic condensation (PIC). Analysis of dielectric ﬁlm quality is carried out via electrical measurements of metal-insulator-metal (MIM) diodes. Anneals at 500 and 700 °C...
