Properties of III-Nitride-Based Polariton and Spin Polariton Diode Lasers
(2018)
The cavity electrodynamic regime of strong coupling of emitter-photon interactions in a semiconductor microcavity gives rise to new light-matter entangled quasiparticles, also known as exciton-polaritons. The non-linear ...
Charge and Exciton Dynamics in Organic Optoelectronic Devices
(2019)
Organic optoelectronics use carbon-based molecules to interface between light and electrical signals. The operation of these devices is determined by the dynamic behaviors of their charges and excited states. For example, ...
Graphene Optoelectronics and Metamaterials.
(2016)
Graphene, the one-atom-thick carbon crystal, represents the first of an entire class of two-dimensional materials. In this thesis, the opportunities of graphene as a building block for optoelectronics and metamaterials are ...
Autonomous Scene Understanding, Motion Planning, and Task Execution for Geometrically Adaptive Robotized Construction Work
(2019)
The construction industry suffers from such problems as high cost, poor quality, prolonged duration, and substandard safety. Robots have the potential to help alleviate such problems by becoming construction co-workers, ...
Optical Quartz Crystal Microbalance (OQCM) for Dual-Mode Analysis
(2018)
Label-free biosensors allow for real-time measurements of the target molecule, providing valuable kinetic data about the unperturbed biological system. Yet, they generally rely on a single transduction mechanism that ...
Separable Inverse Problems, Blind Deconvolution, and Stray Light Correction for Extreme Ultraviolet Solar Images.
(2013)
The determination of the inputs to a system given noisy output data is known as an inverse problem. When the system is a linear transformation involving unknown side parameters, the problem is called separable. A quintessential ...
Advances in Quantitative MRI: Acquisition, Estimation, and Application
(2018)
Quantitative magnetic resonance imaging (QMRI) produces images of potential MR biomarkers: measurable tissue properties related to physiological processes that characterize the onset and progression of specific disorders. ...
Spin Injection, Transport, and Modulation in III-V Semiconductors.
(2012)
Spintronic devices, which aim to utilize the quantum mechanical spin properties of electrons, offer the potential of high-speed and low-power operation with performance possibly exceeding those of conventional charge-based ...
New Methods for Terahertz and Ultrafast Infrared Spectroscopy of Biological Materials and Graphene Buffer Layer
(2019)
The development of advanced optical spectroscopy has always been a frontier in optics and material science. This dissertation develops several new methods for terahertz (THz) and infrared spectroscopy and presents their ...
Probing Heat Transport and Energy Conversion at the Atomic and Single Molecule Scale
(2018)
The study of heat transport and energy conversion constitutes an important subject in modern physics and engineering research. The widely-applied Fourier’s and Planck’s laws have proven to be very useful to describe heat ...
