ASSESSMENT OF ONE-MOMENT AND TWO-MOMENT BULK MICROPHYSICS AND SPECTRAL BIN MICROPHYSICS SCHEMES USING IDEALIZED SUPERCELL SIMULATIONS AND REAL DATA CONVECTIVE-SCALE PREDICTIONS
Johnson, Marcus (2019-05)Optimal hydrometeor parameterization and their associated processes in microphysics schemes (both spectral bin and bulk) continue to evolve as these schemes attempt to match observed hydrometeor complexity. This dissertation ... -
CHARACTERIZATION AND DEVELOPMENT OF SEMICONDUCTOR CASCADE DEVICES
Rassel, SM Shazzad (2018-05-11)Interband cascade lasers (ICLs) are efficient source of mid-infrared light for many applications that require low power consumption and continuous wave (cw) operation at room temperature. In the last decade, remarkable ... -
High-performance InAs-based interband cascade lasers
Jiang, Yuchao (2016-05)Currently, there are only two types of mid-infrared lasers that are capable of continuous-wave (CW) operation above room temperature: quantum cascade (QC) lasers and interband cascade (IC) lasers. Both of them share the ... -
Innovative Growth Techniques and Heterogeneous Structures for PbSe-Based MWIR Photodetectors
McDowell, Lance (2022-12-16)Lead-chalcogenide semiconductor materials such as PbSe are an attractive class of narrow band-gap semiconductors due to their unique optical and electrical properties, finding their way into numerous mid-wave infrared ... -
MICROWAVE AND SURFACE ELECTROMETRY WITH RYDBERG ATOMS

Molecular beam epitaxial growth of interband cascade structures with advances in InAs- and GaSb-based interband cascade lasers
Massengale, Jeremy (2023-04-21)Interband cascade lasers (ICLs) based on the type-II quantum well (QW) active region have attracted much interest over the years, in large part due to their low power consumption. Their operation hinges on two key features; ... -
MOLECULAR BEAM EPITAXY OF ANTIMONY QUANTUM WELLS FOR PROBING TOPOLOGICAL SURFACE STATES
Wickramasinghe, Kaushini (2017)A topoelectronic transition was predicted for an Sb quantum well (QW) as a function of QW thickness. Bulk Sb is a semimetal with a negative bandgap, with neither the conduction band minimum nor the valence band maximum at ... -
Molecular Beam Epitaxy of InAs, GaSb, AlSb Structures for Interband Cascade Devices
Ye, Hao (2016-08)The interband cascade (IC) family of devices has been extended beyond mid-infrared lasers to include photovoltaic (PV) and photodetector (PD) devices. These devices utilize the transition between conduction and valence ... -
MULTIPLE-STAGE INTERBAND CASCADE PHOTOVOLTAIC DEVICES USING 6.1 Å SEMICONDUCTOR MATERIALS
Hinkey, Robert (2013-12-13)Interband cascade photovoltaic (IC PV) structures are an attractive alternative to the conventional long-absorber diode structures currently used for mid-infrared photovoltaic devices. The unique feature of IC PV devices ... -
Resolving DNA Using A Bare Open Narrow Capillary without Sieving Matrix
Zhu, Zaifang (2014-08)DNA molecules encode the hereditary information utilized in all living organisms, including humans. Separating DNA fragments is essential in biological research because it informs us how DNA molecules work and eventually ... -
THERMOPHOTOVOLTAIC DEVICES AND INFRARED PHOTODETECTORS BASED ON INTERBAND CASCADE STRUCTURES
