Photodimerization of Organic Semiconductors in the Strong Coupling Regime

Creator:: Puro, Richard
Abstract:: Organic semiconducting materials have emerged in the last few decades as viable alternatives to inorganics in broad applications from field effect transistors to LEDs to solar cells. Organics provide many benefits over inorganics such as flexibility, sustainability, and reduced cost. However, these materials are more susceptible to degradation in the...

A Study of Charging Behaviors in Organic Semiconductors using Optical Trapping

Creator:: Founds, Graham M.
Abstract:: We measure the charging and discharging of two organic materials, PCBM and ADT-TES-F. These materials are studied through the noncontact method of particle trapping known as Optical Tweezers, where an IR laser is used to constrain the motion of a coated or noncoated silica sphere while its positional data is...

Spectroscopic Ellipsometry on Thin Films of TiO2: Comparing Cauchy and Cody-Loretnz Models in CompleteEASE

Creator:: Kreb, Joseph
Abstract:: Spectroscopic ellipsometry (SE) is used to characterize amorphous and crystalline thin films of TiO2. Amorphous precursor films of TiO2 are deposited by radio frequency magnetron sputtering on fused silica and silicon substrates. Annealing the amorphous precursor films induces them to crystallize into either pure or mixed phases of the three...

Full Text:: EPMA data was affected by the fact that we were originally using the same density for amorphous films

Chiral Topological Defects in Nematic Liquid Crystals and Classical Field Theories

Creator:: Douglas, Brennan
Abstract:: A great variety of topologically protected defects exist in ordinary and exotic states of matter. Some of them are promising candidates for technological applications such as magnetic memory or quantum computers. Others possess some properties of elementary particles that could lead to potential applications in quantum fields. Nematic liquid crystals...

Optoelectronic Properties of a Novel Fungi-derived Pigment

Creator:: Wiesner, Cameron
Abstract:: In industry, there is considerable interest in finding sustainable, renewable materials for use in electronic devices. Pigments derived from spalting fungi are of particular interest due to their longevity in diverse environmental conditions. The focus of my project was to characterizethe properties of a novel, fungi-derived pigment, and to discover...

Exploring the Optical and Electronic Properties of Xylindein, a Fungus-Derived Pigment, as a Sustainable Organic Semiconductor

Creator:: Quinn, Alexander
Abstract:: Xylindein is an organic pigment derived from Chlorociboria aeruginascens and C. aeruginosa fungi that has shown promise as an organic semiconductor. Preliminary estimates of charge carrier mobilities (CCMs) on the order of 0.1 cm2/Vs were calculated from early tests on xylindein thin films, and photocurrents were also observed under laser...

Fabrication and Characterization of Nanoscale Devices made from Molybdenum Disulfide

Creator:: McKay, Zach and McKay, Zachary
Abstract:: Using a simple dry transfer process, I construct and characterize three nanoscale MoS2 devices using current-voltage curves, Raman spectroscopy, optical and atomic force microscopy. I compare these devices, the thinnest of which was few layer ( ≤ 10 nm) MoS₂ capable of showing photoconductance, with a current whose magnitude is...

Is Advection Important? An Examination of the Advective Dynamics of Sensible Heat and Their Influence onSubcanopy Carbon Fluxes in Heterogeneous Terrain

Creator:: Carrigg, Sean Stephen
Abstract:: Abstract Understanding small-scale bio-atmospheric interactions is becoming increasingly important as the global climate continues to change at breakneck speed. A theoretical model of the sensible heat budget of a forest is developed combining conservation equations and concepts from fluid dynamics. Budget components are computationally evaluated using micrometeorological data taken during...
