Weak-supervision Time-series Analysis

Creator:: You, Zeyu
Abstract:: Efficient time-series analysis can impact multiple application domains such as motif discovery in gene analysis or music data, extracting spectro-temporal patterns in acoustic scene analysis, or annotating and classifying electrical bio-signals (such as ECG, EEG, and EMG) for medical applications. Time-series analysis involves a variety of tasks. To predict future...

Molecular Packing-Dependent Exciton and Polari on Dynamics in Anthradithiophene Organic Crystals

Creator:: Van Schenck, Jonathan D. B., Giesbers, Gregory, Kannegulla, Akash, Cheng, Li-Jing, Anthony, John E., and Ostroverkhova, Oksana
Abstract:: Polarization-dependent absorption spectra of two functionalized derivatives of fluorinated anthradithiophene, diF TES-ADT and diF TDMS-ADT, were studied in the crystal phase using a Holstein-like Hamiltonian. For both molecules, the primary contribution to the lowest energy absorption was found to be the S-0-S-1 excitonic transition perturbed by an intermolecular coupling of...

Photophysics of organic semiconductors at the nanoscale

Creator:: Grollman, Rebecca R.
Abstract:: Organic semiconductors are used in a wide variety of applications including transistors,solar cells, and light emitting diodes. These materials are solution-processable,low cost, and tunable. Many successful organic optoelectronic materials utilizeblends of several types of molecules (such as donors and acceptors) in order topromote charge generation. As blends are an inherently...

Electronic and Optical Properties of Organic Semiconductors : Experiment and Simulation

Creator:: Johnson, Brian
Abstract:: The continued development of organic semiconductor materials relies on an understanding of the relationship between optoelectronic properties, molecular structure, and molecular interaction. Several detailed studies of electronic properties in functionalized polyacene materials are presented. A computational model which allows the extraction of charge generation and transport properties from experimental data...

Design of organic ternary blends and small-molecule bulk heterojunctions: photophysical considerations

Creator:: Rajesh, Kallarakkal Ramakrishnan, Paudel, Keshab, Johnson, Brian, Hallani, Rawad, Anthony, John, and Ostroverkhova, Oksana
Abstract:: We explored relationships between photophysical processes and solar cell characteristics in solution-processable bulk heterojunctions (BHJs), in particular: (1) polymer donor:fullerene acceptor:small-molecule (SM) nonfullerene acceptor, (2) polymer donor:SM donor:SM nonfullerene acceptor, and (3) SM donor:SM nonfullerene or fullerene acceptor. Addition of a nonfullerene SM acceptor to “efficient” polymer:fullerene BHJs led to...

Enhanced charge photogeneration promoted by crystallinity in small-molecule donor-acceptor bulk heterojunctions

Creator:: Paudel, Keshab, Johnson, Brian, Thieme, Mattson, Haley, Michael M., Payne, Marcia M., Anthony, John E., and Ostroverkhova, Oksana
Abstract:: We examined sub-nanosecond time-scale charge carrier dynamics in crystalline films of a functionalized anthradithiophene (ADT) donor (D) with three different acceptor (A) molecules. A four-fold enhancement in ultrafast charge carrier separation efficiency was observed in D/A blends with a fullerene acceptor added at 7–10 wt. % concentrations, whereas a gradual...

Analysis of spatial data from terrain models for landslide predictive mapping

Creator:: Santha, Rubini
Abstract:: Landslides are a pervasive hazard that can result in substantial damage to properties and loss of life throughout the world. To understand the nature and scope of the hazard, landslide hazard mapping has been an area of intense research by identifying areas most susceptible to landslides in order to mitigate...

Charge carrier dynamics in organic semiconductors and their donor-acceptor composites: Numerical modeling of time-resolved photocurrent

Creator:: Johnson, Brian, Kendrick, Mark J., and Ostroverkhova, Oksana
Abstract:: We present a model that describes nanosecond (ns) time-scale photocurrent dynamics in functionalized anthradithiophene (ADT) films and ADT-based donor-acceptor (D/A) composites. By fitting numerically simulated photocurrents to experimental data, we quantify contributions of multiple pathways of charge carrier photogeneration to the photocurrent, as well as extract parameters that characterize charge...
