Pore Characterization of Ultralow-k Dielectric Thin Films Using Positronium Annihilation Spectroscopy.
(2008)
In this thesis, a series of nanoporous ultralow dielectric constant (ULK) thin films fabricated using spin-coating and sacrificial pore generators (degradable porogens embedded in a host matrix) were studied as a function ...
Quantum Optical Applications in Spectroscopy: Investigations of Entangled Two-Photon Absorption and Entangled Two-Photon Excited Fluorescence in Organic Dendritic Systems.
(2010)
Entangled states of light have been utilized successfully in a wide variety of experiments and applications. This dissertation will discuss the application of entangled states of light toward spectroscopy wherein entangled ...
Sum Frequency Generation Vibrational Spectroscopy Investigation of Buried Polymer and Organic Interfaces.
(2009)
It is difficult to elucidate buried interfaces because of the lack of appropriate analytical techniques. In this thesis, it was shown that sum frequency generation vibrational spectroscopy (SFG) can be used to probe ...
Nonlinear Optical Enhancement from Aggregate and Ensemble Effects in Organic Systems.
(2011)
Organic optoelectronics provide several advantages over traditional Si based systems. These advantages are typically cost, ease of manufacturing, and environmental impact. One area of particular interest in the field of ...
Binary Mixtures in Linear Convection Arrays
(Wiley Periodicals, Inc.(Springer Netherlands, 2023-01-03)
We numerically investigated the dynamics of a mixture of finite-size active and passive disks in a linear array of two-dimensional convection rolls. The interplay of advection and steric interactions produces a number of ...
Effect of Nanoscale Confinement on Ultrafast Dynamics of Singlet Fission in TIPS-Pentacene
(WILEY-VCH, 2022-11-18)
Singlet fission (SF) is a phenomenon for the generation of a pair of triplet excitons from anexcited molecule in singlet electronic state interacting with another adjacent molecule in its ground electronic state. By ...
