Fabrication Of Al:Hfo2 Gate Dielectric Mosfets, George Mcmurdy

Theses

Replacing the traditional SiO2 gate oxide in a MOSFET with ferroelectric HfO2 creates a 1T memory device referred to as a FeFET. The bi-stable polarization states cause a retained threshold voltage shift known as the memory window. Ferroelectric HfO2 offers a number of material and electrical advantages over perovskite based ferroelectrics such as PZT or SBT. Due to its use as a high-k dielectric, the ALD capability and etch characteristics of hafnium oxide are well documented. Ferroelectric HfO2 has been shown to be thermally stable up to 1000 C, making gate first FeFET processes feasible. Electrically, HfO2 is capable of …

Three Dimensional Digital Alloying With Reactive Metal Inks, Chaitanya G. Mahajan

Theses

3D printing of multifunctional components using two or more materials is a rapidly growing area of research. Metallic alloy inks have been used with various 3D printing techniques to create functional components such as antennas, inductors, resistors, and biocompatible implants. Most of these printing techniques use premixed metallic alloy inks or nanoalloy particles with a fixed composition to fabricate the functional part. Since the properties of alloys vary with changes in the elemental composition, a printing process which could digitally dispense alloy inks having specific desired compositions would enable different functionalities and be highly desirable.

Semiconductor Nanofabrication Via Metal-Assisted Chemical Etching: Ternary Iii-V Alloys And Alternative Catalysts, Thomas S. Wilhelm

Theses

The increasing demand for complex devices that utilize three-dimensional nanostructures has incentivized the development of adaptable and versatile semiconductor nanofabrication strategies. Without the introduction and refinement of methodologies to overcome traditional processing constraints, nanofabrication sequences risk becoming obstacles that impede device evolution. Crystallographic wet-chemical etching (e.g., Si in KOH) has historically been sufficient to produce textured Si surfaces with smooth sidewalls, though it lacks the ability to yield high aspect-ratio features. Physical and chemical plasma etching (e.g., reactive-ion etching) evolved to allow for the creation of vertical structures within integrated circuits; however, the high energy ion bombardment associated with dry …

Directional Notches As Microstructures To Promote Nucleation And Heat Transfer In Pool Boiling, Callum Mclaughlin

Theses

Heat generation in electronic hardware has become a major limiting factor in achieving maximum efficiency in modern computer parts. Classically forced flow convection systems are used to remove this heat at high rates but can be costly to implement and can take up space that may be needed for other critical components. In response to this, systems that use fewer parts scale in compact spaces are needed. In these situations, pool boiling as a heat transfer mechanism can excel. Pool boiling removes heat through the evaporation of fluid. On a flat surface pool boiling is chaotic and this random nature …

App Review Analysis Via Active Learning: Reducing Supervision Effort Without Compromising Classification Accuracy, Venkatesh Thimma Dhinakaran

Theses

Automated app review analysis is an important avenue for extracting a variety of requirements-related information. Typically, a first step toward performing such analysis is preparing a training dataset, where developers(experts) identify a set of reviews and, manually, annotate them according to a given task. Having sufficiently large training data is important for both achieving a high prediction accuracy and avoiding over-fitting. Given millions of reviews, preparing a training set is laborious.We propose to incorporate active learning, a machine learning paradigm,in order to reduce the human effort involved in app review analysis. Our app review classification framework exploits three active learning …

Investigating Dynamic Stiffening And Softening Of A System Of Colloids Cross-Linked Via Polymers, Elisabeth Rennert

Theses

With the goal of ultimately deciphering the design principles for biomimetic materials that can autonomously stiffen and soften, we investigate colloids as a model system that can dynamically transition from fluid-like (sol) to gel-like (gel) when crosslinked with polymers. The model was first developed with colloids only, interacting via a Lennard-Jones potential and undergoing Brownian dynamics, with experimentally relevant parameters, to test and refine the simulation. We then added polymer crosslinkers that connect the colloids via an attractive spring force, and investigate resulting collective properties, such as the time needed for the formation of system spanning networks and the elastic …

Point Spread Function And Modulation Transfer Function Engineering, Jacob Wirth

Theses

A novel computational imaging approach to sensor protection based on point spread function (PSF) engineering is designed to suppress harmful laser irradiance without significant loss of image fidelity of a background scene. PSF engineering is accomplished by modifying a traditional imaging system with a lossless linear phase mask at the pupil which diffracts laser light over a large area of the imaging sensor. The approach provides the additional advantage of an instantaneous response time across a broad region of the electromagnetic spectrum. As the mask does not discriminate between the laser and desired scene, a post-processing image reconstruction step is …

Human Auditory Discrimination Of Bottlenose Dolphin Signature Whistles Masked By Noise: Investigating Perceptual Strategies For Anthropogenic Noise Pollution, Evan L. Morrison

Theses

Anthropogenic masking noise in the world’s oceans is known to impede many species’ ability to perceive acoustic signals, but little research has addressed how this noise pollution affects the detection of bioacoustic signals used for communication. Bottlenose dolphins (Tursiops truncatus) use signature whistles which contain identification information. Past studies have shown that human participants can be used as models for dolphin hearing, but most previous research investigated echolocation. In Experiment 1, human participants were tested on their ability to auditorily discriminate among signature whistles from three dolphins. Participants’ performance was nearly errorless (M = 98.8%). In Experiment 2, participants identified …
