Electronic Conduction and Ionic Diffusion in (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-based Thin Films, Electronic Conduction and Ionic Diffusion in (Bi0.5Na0.5)TiO3-(Bi0.5K0.5)TiO3-based Thin Films

Creator:: Walenza-Slabe, Joel
Abstract:: Solid solutions based on the perovskite ferroelectrics Bi₀.₅Na₀.₅TiO₃ (BNT) and Bi₀.₅K₀.₅TiO₃ (BKT) might someday replace current Pb-based ferroelectric and piezoelectric devices. This is one goal of the Restrictions on Hazardous Substances (RoHS) guidelines seeking to limit Pb in consumer devices. Although the Bi-based ferroelectrics are well suited to the task...

Synthesis and characterization of Pb(Zr,Ti)O₃ thin films for microelectromechanical systems

Creator:: Brookshire, Kirsten L.
Abstract:: Pb(Zr,Ti)O₃ (PZT) is a very attractive material for use in piezoelectric-based microelectromechanical systems (MEMS) due to its high piezoelectric coefficients and ability for large displacements with relatively low applied fields (as compared to electrostatic-based MEMS). The piezoelectric effect is strongly anisotropic, thus it is very desirable to control the crystallographic...

Developing New Routes for Mechanical Characterization of Metal-Organic Frameworks

Creator:: Maack, Bryan A.
Abstract:: Metal-organic frameworks (MOFs) represent an exciting, new class of porous materials. Their hybrid organic-inorganic structure opens up near infinite possibilities to tune and design their structure for specific properties and applications. A new generation of flexible MOFs, following a generation of stiff MOFs, has created additional design space and complexity....

The optimization of thin film p-CuO/n-ZnO heterostructures for use in selective gas detection

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...

Thin Films via Chemical Solution Deposition Synthesis from the (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-Bi(Mg₀.₅Ti₀.₅)O₃ Ternary System

Creator:: Mendez, Jose Eduardo
Abstract:: The ternary system (Bi₀.₅Na₀.₅)TiO₃-(Bi₀.₅K₀.₅)TiO₃-Bi(Mg₀.₅Ti₀.₅)O₃ (BNT-BKT-BMgT) was explored along the [75-(x 2) ]Bi₀.₅Na₀.₅TiO₃ - [25-(x 2)]Bi₀.₅K₀.₅TiO₃ - [x]Bi(Mg₀.₅Ti₀.₅)O₃ composition line. Thin films were fabricated using chelated mixing route solutions spin cast onto platinized silicon substrates. Processing parameters such as: excess cation molar%, solution molality, and crystallization temperatures, for composition where x=0,...

Chemical Solution Deposition and Advanced Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

Creator:: Mason, Ashley D.
Abstract:: Piezoelectric materials convert mechanical strain into a dielectric displacement, as well as the converse, allowing these materials to be used as sensors, actuators, and transducers. Currently, lead zirconate titanate (PZT) is the primary material used in these applications. Due to environmental toxicity and safety concerns associated with Pb, development of...

Development of bi-based lead-free piezoelectric materials : thin film piezoelectric materials via PVD and CSD routes

Creator:: Jeon, Yu Hong
Abstract:: Piezoelectric materials have been widely used in electromechanical actuators, sensors, and ultrasonic transducers. Among these materials, lead zirconate titanate Pb(Zr[subscript 1‐x]Ti[subscript x])O₃ (PZT) has been primarily investigated due to its excellent piezoelectric properties. However, environmental concerns due to the toxicity of PbO have led to investigations into alternative materials systems....

Bi-based perovskite solid solutions for high energy density thin films

Creator:: Emerson, Morgan Rose
Abstract:: Electrical energy storage devices are currently the main limiting factor in many electrical devices and with the increasing demands placed on electrical power over fossil fuels, high energy density materials are essential. Previous research by Huang et al. on bulk (1-x)Bi(Zn₁/₂Ti₁/₂)O₃-xABO₃ solid solution systems led to the discovery of an...

Development of perovskite thin films for use in piezoelectric based microelectromechanical systems

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...

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...
