Anomalous diffusion of Ga and As from semi-insulating GaAs substrate into MOCVD grown ZnO films as a function of annealing temperature and its effect on charge compensation

Creator:: Biswas, Pranab, Halder, Nripendra N., Kundu, Souvik, Banerji, P., Shripathi, T., and Gupta, M.
Abstract:: The diffusion behavior of arsenic (As) and gallium (Ga) atoms from semi-insulating GaAs (SI-GaAs) into ZnO films upon post-growth annealing vis-`a-vis the resulting charge compensation was investigated with the help of x-ray photoelectron spectroscopy (XPS) and secondary ion mass spectroscopy. The films, annealed at 600 °C and 700 °C showed...

Effect of band offset on carrier transport and infrared detection in InP quantum dots/Si nano-heterojunction grown by metalorganic chemical vapor deposition technique

Creator:: Halder, Nripendra N., Biswas, Pranab, Nagabhushan, B., Kundu, Souvik, Biswas, D., and Banerji, P.
Abstract:: Epitaxy of III-V semiconductors on Si gets recent interest for next generation system on heterogeneous chip on wafer. The understanding of band offset is thus necessary for describing the charge transport phenomenon in these heterojunctions. In this work, x-ray photoemission spectroscopy has been used to determine the band offsets in...

Evaluation of High Pressure Processing Kinetic Models for Microbial Inactivation Using Standard Statistical Tools and Information Theory Criteria, and the Development of Generic Time-Pressure Functions for Process Design

Creator:: Serment-Moreno, Vinicio, Fuentes, Claudio, Barbosa-Cánovas, Gustavo, Torres, José Antonio, and Welti-Chanes, Jorge
Abstract:: Generic kinetic models for microbial inactivation by high pressure processing (HPP) would accelerate the development of commercial applications. The aim of this work was to develop a generic model obtained by fitting peer-reviewed microbial inactivation data (124 kinetic curves) to first order kinetics (LKM), Weibull (WBLL), and Gompertz (GMPZ) primary...

Design for Clean Technology Adoption: Application of Discrete Choice Analysis and the Theory of Planned Behavior for Development Engineering

Creator:: Pakravan, Mohammad H.
Abstract:: Clean technologies can address multiple challenges associated with climate change, environmental protection, and human health. However, the impact desired by introduction of such technologies is achievable only if new options effectively replace inefficient, conventional practices. This ‘design for adoption’ requires understanding of user motivations, associated beliefs, context of use, and...

Novel nanocomposite synthesis for high-performance thermoelectrics

Creator:: Eilertsen, James S.
Abstract:: Thermoelectric materials are playing a larger role in the global effort to develop diverse, efficient, and sustainable energy technologies: primarily through power-generating thermoelectric modules. The principal components of thermoelectric modules are solid-state thermoelectric materials – typically heavily doped semiconductors – that convert heat directly into electricity. However, this conversion efficiency...

An evaluation of a water, sanitation, and hygiene (WASH) program for rural communities in northern Afghanistan

Creator:: Costello, Denise H.
Abstract:: The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...

Structure-property relationships of oxides with hexagonal AMO₃ and brownmillerite related structures

Creator:: Jiang, Peng
Abstract:: Transition metal oxides exhibit potential in various application fields due to the special d-electrons. Solid state chemistry focuses on discovering the structure-property relationships. The work in this thesis mainly discusses compounds with hexagonal or brownmillerite-type structure and their practical properties. Hexagonal YIn[subscript 1-x]Fe[subscript x]O₃ (x = 0-0.3, 0.7-1.0) phases have...

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...

Biophysical Characterization of the Yorkie-Mask Complex

Creator:: Bessette, Hannah
Abstract:: Yes-associated protein (YAP) in mammals and Yorkie (Yki) in Drosophila are functionally homologous proteins that partner with transcription factors to promote cell proliferation. The Drosophila protein Mask and its mammalian homolog MASK1 are examples of transcription factors that are essential for Yki/ YAP to drive transcription of target genes. Increased...
