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...

Electrochemical deposition of thin film CuGaSe₂ for photovoltaics

Creator:: Permanasari, Rina
Abstract:: CuGaSe₂/CuInSe₂ tandem junction solar cell is currently being pursued to be a low cost and high efficiency renewable energy source. A reported theoretical efficiency of 33.9% solar cells has been the motivation to fabricate CuGaSe₂ films in a simple and low cost method. Electrodeposition is a potentially suitable method to...

Atomic Layer Deposition (ALD) Process Development of Nb-doped TiO₂ as a Transparent Conducting Oxide (TCO) and ALD of HfO₂/Nb₂O₅ Bilayers as Insulating Barriers for Metal/Insulator/Insulator/Metal (MIIM) Diodes

Creator:: Lin, Shijia
Abstract:: Transparent conductive oxides (TCOs), primarily indium doped tin oxide, have been widely used in numerous fields since decades ago, such as solar cells, displays, OLEDs and ‘smart windows’ etc. Owing to the scarcity of indium, there is a great demand for new alternative materials. Metal/insulator/metal (MIM) diodes are a critical...

Optical Analysis of Titania : Band Gaps of Brookite, Rutile and Anatase

Creator:: Lance, Ryan A.
Abstract:: The optical transition in high-fraction polymorphs of titania (TiO2) were investigated to determine the band gap behavior of the most common polymorphs—brookite, rutile, and anatase—the values of which are varied in the literature. The direct optical band gaps of brookite, rutile, and anatase, were determined to be 3.37(7)eV, 3.41(11)eV and...

Electrically tunable thin-film inductors based on synthetic antiferromagnet cores

Creator:: An, Na
Abstract:: The objective of this research is to demonstrate the feasibility of implementing electrically tunable on-chip inductors based on synthetic antiferromagnet (SAF) cores. This thin film magnetic core is made of a magnetic bi-layer antiferromagnetically coupled through a nonmagnetic spacer layer. An energy model is developed to investigate the magnetic behavior...

Modeling, Fabrication, and Characterization of Magnetic Thin Films for Integrated Inductor and MRAM Applications

Creator:: Buford, Benjamin
Abstract:: Magnetic thin films have potential to improve devices such as on-chip inductors, and enable new technologies such as magnetic random access memory (MRAM). The use of magnetic cores in on-chip inductors is typically limited to applications well under 1 GHz. At higher frequencies, the performance of the magnetic core is...

Study of Interphase in Polylactic Acid and Cellulose Nanocrystal Composite Films

Creator:: Rao, Pratish Ramesh
Abstract:: Polylactic acid (PLA), a renewable material, is used widely in a variety of commercial and specialty applications. However, certain limitations such as high temperature stability and brittleness limit its applicability. This problem is addressed by reinforcing PLA with a variety of materials but the process gives rise to different issues...
