DC/AC Stability of In-Ga-Zn-O Thin-Film Transistors

Creator:

Zhou, Fan

Abstract:

The electrical stability of amorphous indium-gallium-zinc oxide (a-IGZO) thinfilmtransistors (TFTs) is investigated for flat-panel display applications. Althoughproducts incorporating a-IGZO TFT backplanes are already commercially available,e.g., iMac with 5K retina display, technical challenges need to be addressed for nextgenerationapplications, e.g., active-matrix organic light-emitting diode displays.Device stability is one crucial issue. The...

Interlayer Electronic Interactions in Twisted and Stacked Bilayer Graphene

Creator:

Patel, Hiral

Abstract:

The photophysical properties of two-dimensional (2D) layered van der Waals (vdW) materials, and their heterostructures are manifestly distinct from crystalline bulk materials. Recently, the discovery of new 2D vdW materials and strongly-bound interlayer excitons in these materials has created a new branch in nanoscience. As such, there are a number...

CoLocalized Excitation Emission Resolution : A CLEER approach for multicolor fluorescence analysis

Creator:

Almlie, C. Kyle

Abstract:

Fluorescence has proven to be a robust and powerful method of analysis in numerous fields: forensics, pharmaceutics, geology, food science, and environmental sciences have all developed a large collection of fluorescence instruments and methods to overcome application-specific challenges. Biological applications saw the same development of a fluorescence toolkit with methods...

Electron-electron interaction driven phenomena in carbon nanotube devices

Creator:

Aspitarte, Lee

Abstract:

CNTs also offer new opportunities to study new science and develop new technology enabled by their strong electron-electron (e-e) interactions. The lack of dielectric screening inherent in nanoscale structures like CNTs leads to strong e-e interactions, which produce unique physical phenomena. In this thesis, we study the effects of strong...

Dissertation
Development of Cu-based Thin Films for Optoelectronic Applications

Creator:

Angelos, Gregory S.

Abstract:

CIGS and CdTe based commercial thin-ﬁlm solar cells (TFSCs) require an absorber thickness greater than 2 µm and 4 µm, respectively, to adequately absorb the solar spectrum. To efficiently extract photoexcited electrons, these TFSCs require relatively defect-free absorbers with high-minority carrier mobility (> 100 cm2V−1s−1) and long lifetime (> 10...

Development of Amorphous Metal Thin Films for Thermal Inkjet Printing and Microelectronics

Creator:

McGlone, John M.

Abstract:

Due to a lack of grain boundaries, an amorphous metal thin film (AMTF) possesses advantageous mechanical properties and enhanced chemical stability that is potentially useful for thermal inkjet (TIJ) printing applications. The use of an AMTF as a TIJ resistor or cavitation plate could lead to a thinner TIJ cavitation...

Dissertation
Experimental Study of Nucleate Boiling Bubble Dynamics and Heat Transfer Enhancement on Printed Bi-functional Surfaces

Creator:

David, Michele

Abstract:

Boiling heat transfer is studied for its ability to dissipate high fluxes and achieve heat transfer coefficients two orders of magnitude greater than single-phase heat transfer systems. Heater surface enhancement with increased surface area, varied geometry, wettability contrast and micro/nano-structures can further enhance boiling heat transfer performance through bubble nucleation...

Masters Thesis
Terahertz Induced Non-linear Electron Dynamics in Nanoantenna Coated Semiconductors at the Sub-picosecond Timescale

Creator:

Stickel, Andrew

Abstract:

This dissertation is an exploration of the material response to Terahertz (THz) radiation. Specifically we will explore the ultrafast electron dynamics in the nonperturbative regime in semiconductors that have been patterned with nanoantenna arrays using broadband, high intensity, THz radiation. Three main semiconductor materials will be studied in this work....

Reflection and Dissection in Engineering Education : Exploring Critical Elements of Active Learning and their Roles in Course Structures

Creator:

Keeler, Jessie

Abstract:

This thesis focuses on active learning through four different studies that include metacognitive and cognitive aspects of learning designs to support active learning and a contextual analysis of the implementation of teaching tools used in active learning. The first three investigate important elements of active learning whereas the fourth study...

Masters Thesis
Zero Kinetic Energy Photoelectron Spectroscopy of Polycyclic Aromatic Hydrocarbons

Creator:

Harthcock, Colin

Abstract:

In this dissertation, I describe spectroscopic studies of jet-cooled polycyclic aromatic hydrocarbons (PAH) and one nitrogen substituted PAH (PANH) using pulsed field zero kinetic energy (ZEKE) photoelectron spectroscopy and resonantly enhanced multiphoton ionization (REMPI) spectroscopy. Recently, there has been a demand for far-infrared (FIR) spectral information of astrophysically relevant molecules...
