  • 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...

  • 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....

  • Sputtered Pb(Zr0.52Ti0.48)O3 (PZT) thin films on copper foil substrates, Sputtered Pb(Zr₀.₅₂Ti₀.₄₈)O₃ (PZT) thin films on copper foil substrates

    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...

  • Atomic layer deposition of nanolaminate Al₂O₃-Ta₂O₅ and ZnO-SnO₂ films

    Creator:
    Smith, Sean Weston
    Abstract:
    Thin films are an enabling technology for a wide range of applications, from microprocessors to diffusion barriers. Nanolaminate thin films combine two (or more) materials in a layered structure to achieve performance that neither film could provide on its own. Atomic layer deposition (ALD) is a chemical vapor deposition technique...

  • Selective self-assembly of biogenic silica assisted by layer-by-layer deposition and inkjet printing

    Creator:
    Wang, Wei
    Abstract:
    Nature is an inspirational source of silica structures that possess unique optical properties. A few classes of organisms fabricate metal oxides with nanoscale features by a bottom-up self assembly process. In particular, diatoms are a prolific class of single-celled algae that possess silica shells or “frustules” with intricate submicron scale...

  • Growth and characterization of the p-type semiconductors SnS and BiCuOSe

    Creator:
    Francis, Jason
    Abstract:
    BiCuOSe and SnS are layered, moderate band gap (ε[subscript G] ≈ 1 eV) semiconductors that exhibit intrinsic p type conductivity. Doping of BiCuOSe with Ca results in a slight expansion of the lattice and an increase of the hole concentration from 10¹⁸ cm⁻³ to greater than 10²⁰ cm⁻³. The large...

  • The chemistry and device applications of amorphous thin-film interfaces

    Creator:
    Knutson, Christopher C.
    Abstract:
    Solid-state amorphous materials show amazing promise in thin-film electronics. The interface-to-bulk ratio of thin films makes interfacial chemistries of these systems of utmost importance. Thin films of amorphous metals, dielectrics and semiconductors have novel chemistries that are not only based upon their elemental constituent makeup, but also based upon the...

    Creator:
    Fast, Dylan Braucht
    Abstract:
    In this dissertation, the structure and electronic properties of multiple metal oxide thin films are characterized and presented. Prompt inorganic condensation (PIC) of metal-oxo and –hydroxo clusters was evaluated as a technique for making metal oxide clusters in two separate studies. The first focuses on the synthesis of lithium niobate...
