A novel method for zinc oxide nanowire sensor fabrication

Creator:: Pelatt, Brian D.
Abstract:: Interest in nanomaterials is motivated partly by their potential for sensor arrays to detect different gases. Nanowires in particular are of interest because their high surface-to-volume ratio promises the possibility of high sensitivity. However, because of their discrete quasi-one-dimensional geometry, electrical integration of nanowires into photolithographically defined devices and circuits...

A Wide Modulation Range and PVT-Tolerant Spread-Spectrum Modulation Clock Generator

Creator:: Sun, Hyuk
Abstract:: This dissertation presents a phase domain in-loop-bandwidth spread-spectrum clock generation technique. In this proposed technique, a charge-based discrete-time loop filter is proposed to enable the phase domain in-loop-bandwidth spread-spectrum modulation without a delta-sigma modulator or time-to-digital converter. The in-loop-bandwidth modulation technique maximizes the loop bandwidth to improve phase noise suppression...

Adaptive Streaming Methods using Dual Protocols and Reinforcement Learning

Creator:: Gatimu, Kevin
Abstract:: The ubiquity of high quality video and proliferation of mobile devices has contributed to an unprecedented rise in video consumption. HTTP, in conjunction with adaptive streaming, has become the de facto mechanism for delivering the vast majority of video as it readily caters to heterogeneous networks and devices. This dissertation...

Al-In-Sn-O thin-film transistors

Creator:: Stewart, Kevin A.
Abstract:: The aim of the research undertaken for this thesis was to develop a new high-performance amorphous oxide semiconductor (AOS) for use as a channel layer in a thin-film transistor (TFT). AOS TFTs offer higher electron mobility than the established amorphous silicon based technology. A new channel material comprised of aluminum...

Amorphous oxide semiconductor thin-film transistor ring oscillators and material assessment

Creator:: Sundholm, Eric Steven
Abstract:: Amorphous oxide semiconductor (AOS) thin-film transistors (TFTs) constitute the central theme of this thesis. Within this theme, three primary areas of focus are pursued. The first focus is the realization of a transparent three-stage ring oscillator with buffered output and an output frequency in the megahertz range. This leads to...

Amorphous oxide semiconductors in circuit applications

Creator:: McFarlane, Brian Ross
Abstract:: The focus of this thesis is the investigation of thin-film transistors (TFTs) based on amorphous oxide semiconductors (AOSs) in two circuit applications. To date, circuits implemented with AOS-based TFTs have been primarily enhancement-enhancement inverters, ring oscillators based on these inverters operating at peak frequencies up to ~400 kHz, and two-transistor...

Assessment of High Mobility Oxide Thin-Film Transistors

Creator:: Stewart, Kevin A.
Abstract:: The trend towards higher resolution, faster refresh rate active-matrix liquid-crystal displays (AMLCDs) as well as the emergence of active-matrix organic light-emitting diode (AMOLED) displays is driving the demand for amorphous oxide semiconductor thin-film transistors (AOS TFTs) with higher mobility. A physics-based model for carrier transport in an amorphous semiconductor is...

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...

Atomic Layer Processing for Next-Generation Microelectronic Materials

Creator:: Holden, Konner E. K.
Abstract:: Atomic layer deposition (ALD) is an enabling technique for many new micro- and nanoscale technologies. The self-limiting surface chemical reactions by which ALD fundamentally operates give rise to uniquely high precision (atomic) control over deposited film thickness, uniformity over large areas, and conformality over complex and extreme topographies. One such...

Comprehensive depletion-mode modeling of oxide thin-film transistors

Creator:: Zhou, Fan
Abstract:: The primary focus of this thesis is modifying the comprehensive depletion-mode model and extending its applicability to p-channel thin-film transistor (TFT) behavior and subthreshold (subpinchoff) operation. The comprehensive depletion-mode model accurately describes depletion-mode TFT behavior and establishes a set of equations, different from those obtained from square-law theory, which can...
