Temperature dependence of exciton and charge carrier dynamics in organic thin films

Creator:: Platt, A. D., Kendrick, M. J., Loth, M., Anthony, J. E., and Ostroverkhova, O.
Abstract:: We report on physical mechanisms behind the temperature-dependent optical absorption, photoluminescence (PL), and photoconductivity in spin-coated films of a functionalized anthradithiophene (ADT) derivative, ADT-triethylsilylethynyl (TES)-F, and its composites with C₆₀ and another ADT derivative, ADT-TIPS-CN. Measurements of absorption and PL spectra, PL lifetimes, and transient photocurrent were performed at temperatures...

Eaffective Ecopoetics as a Practice for Feeling a World in Crisis

Creator:: Platt, Benjamin D.
Abstract:: Discussions of ecopoetics often seek to investigate how poetics as a form can be rendered more ecological, often in contrast to nature poetry. These conversations tend to concentrate on this generic contrast and the formal qualities of an ecological poetics. Ecopoetics as a field emerged largely as a response to...

Copper and iron chalcogenides for efficient solar absorption

Creator:: Platt, Heather A. S.
Abstract:: This dissertation outlines two approaches for improving the efficiency and reducing the cost of photovoltaic energy generation. First, the structures of known binary copper and iron compounds are used to choose the promising compositions Fe₂XS₄ (X = Si, Ge), Cu₃TaQ₄ (Q = Se, Te), and BaCuQ'F (Q' = S, Se,...

Examining fire-prone forest landscapes as coupled human and natural systems

Creator:: Spies, Thomas A., White, Eric M., Kline, Jeffrey D., Fischer, A. Paige, Ager, Alan, Bailey, John, Bolte, John, Koch, Jennifer, Platt, Emily, Olsen, Christine S., Jacobs, Derric, Shindler, Bruce, Steen-Adams, Michelle M., and Hammer, Roger
Abstract:: Fire-prone landscapes are not well studied as coupled human and natural systems (CHANS) and present many challenges for understanding and promoting adaptive behaviors and institutions. Here, we explore how heterogeneity, feedbacks, and external drivers in this type of natural hazard system can lead to complexity and can limit the development...

Organic semiconductor composites: influence of additives on the transient photocurrent

Creator:: Day, Jonathan, Platt, Andrew D., Ostroverkhova, Oksana, Subramanian, Sankar, and Anthony, John E.
Abstract:: We report on the effect of various guest molecules added to a functionalized anthradithiophene (ADT) host on photoexcited charge carrier dynamics in solution-deposited thin films, from ~100 ps to >100 μs after photoexcitation with 100 fs laser pulses. An addition of 2 and 5 wt % of C60 to a...

A Burning Problem: Social Dynamics of Disaster Risk Reduction through Wildfire Mitigation

Creator:: Charnley, Susan, Poe, Melissa R., Ager, Alan A., Spies, Thomas A., Platt, Emily K., and Olsen, Keith A.
Abstract:: Disasters result from hazards affecting vulnerable people. Most disasters research by anthropologists focuses on vulnerability; this article focuses on natural hazards. We use the case of wildfire mitigation on United States Forest Service lands in the northwestern United States to examine social, political, and economic variables at multiple scales that...

Band alignment at the BaCuSeF/ZnTe interface

Creator:: Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Barati, Alireza, Klein, Andreas, and Jaegermann, Wolfram
Abstract:: In situ photoemission spectroscopy experiments are used to characterize the interface between ZnTe and the wide band gap p-type semiconductor BaCuSeF. The contact is characterized by a null valence-band offset, a large conduction-band offset, and a chemically graded interface. By applying the transitivity rule for band offset and on the...

Electronic properties of BaCuChF (Ch = S,Se,Te) surfaces and BaCuSeF/ZnPc interfaces

Creator:: Zakutayev, Andriy, Tate, Janet, Platt, Heather A. S., Keszler, Douglas A., Hein, Corinna, Mayer, Thomas, Klein, Andreas, and Jaegermann, Wolfram
Abstract:: BaCuChF (Ch=S,Se,Te) surfaces and BaCuSeF interfaces with zinc phthalocyanine (ZnPc) were studied by photoelectron spectroscopy. BaCuChF compounds oxidize when exposed to ambient atmosphere. Se capping layers were studied as a means to produce representative surfaces for photoelectron spectroscopic measurements. Decapped BaCuSeF surfaces remain O-free and C-free when the Se layer...
