Dependence of Radiant Optical Magnetization on Material Composition
(2018)
The realization of strong optical magnetism in nominally “non-magnetic” media could lead to novel forms of all-optical switching, energy conversion, or the generation of large (oscillatory) magnetic fields without ...
Optical and Theoretical Studies of Excitons in Few-Layer Lead Iodide.
(2015)
Optical measurements and first-principles calculations of few-layer lead iodide (PbI2) crystals are presented in this work. Results indicate that the band structure and exciton energies change dramatically from direct-gap ...
Plasmonic Waveguide Lithography for Patterning Nanostructures with High Aspect-Ratio and Large-Area Uniformity
(2018)
The rapid development of the semiconductor industry in the past decades has driven advances in nano-manufacturing technologies towards higher resolution, higher throughput, better large-area uniformity, and lower manufacturing ...
Nonlinear Optical Spectroscopy of Single Walled Carbon Nanotubes.
(2012)
Single Walled Carbon Nanotubes (SWCNTs) have attracted immense attention for making molecular-scale transistors to replace silicon transistors in the post-CMOS era. Moreover, their direct bandgap nature, along with the ...
High Resolution Organic Vapor Jet Printing of Phosphorescent Organic Light Emitting Diode Arrays.
(2013)
Organic light emitting diodes (OLEDs) are widely used in mobile devices due to their thin form factor, wide color gamut, and high efficiency. The introduction of OLEDs into televisions and monitors has been slowed, in ...
Carrier Transport in Auger-Suppressed Infrared Detector Materials
(2019)
State of the art infrared detectors can operate at high efficiency and low noise throughout the infrared wavelength range. However, MWIR and LWIR detectors are still limited by very low operating temperatures in order to ...
Subwavelength Dielectric Grating-based Broadband Reflectors and Narrowband Transmission Filters.
(2014)
This dissertation includes investigations on infrared mirrors and filters for next generation thermal imaging and spectrometer-on-a-chip applications operating in the long-wavelength infrared (LWIR, 8-15 microns) spectral ...
Operational Stability and Charge Transport in Fullerene-Based Organic Solar Cells
(2018)
Organic photovoltaic cells are approaching commercially-viable levels of performance for a variety of applications--particularly those which make use of the unique transparency, flexibility, and ultra-thin form factor that ...
GNSS-R Remote Sensing of the Ocean: Surface Waves and Related Phenomena
(2016)
In this thesis, we explore several fundamental issues in GNSS-R remote sensing. Global Navigation Satellite System - Reflectometry (GNSS-R) is a relatively young remote sensing technique proposed to measure geophysical ...
Multiple Volume Scattering in Random Media and Periodic Structures with Applications in Microwave Remote Sensing and Wave Functional Materials
(2016)
The objective of my research is two-fold: to study wave scattering phenomena in dense volumetric random media and in periodic wave functional materials. For the first part, the goal is to use the microwave remote sensing ...
