Study of hot carrier dynamics and relaxation in metal halide perovskites
(2023-05)
Metal halide perovskites are a promising class of solution-based semiconductors
with significant potential for optoelectronic devices, including hot carrier solar cells
that are proposed to achieve higher efficiency than ...
Magneto-optical properties of indium antimide based quantum wells.
(2001)
We observe electron spin resonance using FIR laser spectroscopy in symmetric and asymmetric InSb quantum wells over a wide range of magnetic field and the Landau level index. The behavior of the asymmetric wells at low ...
R-matrix theory and device modeling.
(2005)
Novel experimental techniques allow us to fabricate very small semiconductor devices such that the electron mean free path is larger than the size of the device. The macroscopic properties of these quantum mechanical devices ...
High-precision measurements of alkanethiol self-assembled monolayer structure with scanning tunneling microscopy
(2020)
This thesis describes a measurement methodology and set of tools for measuring scanning tunneling microscope images of crystals at picometer length scales. We use the crystal structure present in high-quality scanning ...
An investigation of the properties of indium antimonide/aluminum(x) indium(1-x) antimonide quantum wells.
(2002)
This work investigates InSb/AlxIn1- xSb quantum wells through the use of Fourier Transform Infrared (FTIR) Spectroscopy. In addition to briefly examining excitonic transitions in undoped square wells, this work covers a ...
Investigation into molecular beam epitaxial growth and characterization of InGaAs structures and InAs superlattices
(2014-05)
(1) InGaAs quantum wells have been experimentally studied for their potential application in electronic devices. The narrow band gap of InGaAs lead to smaller effective masses for electrons and holes, which results in ...
Novel phenomena in confined electronic systems.
(2007)
Modern experimental methods have made it possible for physicists to investigate matter in extreme conditions. Two of the most extreme conditions are low temperature and low dimensionality. Fabricated semiconductor or metal ...
Polymer electrolyte conductivity and the Vogel equation.
(2004)
The frequency-dependent conductivity of an amorphous polymer electrolyte is examined. It is shown that the frequency-dependent conductivity of polymer electrolytes exhibit many of the same properties as ion conducting ...
Spin resolved cyclotron resonance in indium antimonide quantum wells.
(2005)
In this study we looked at spin resolved cyclotron resonance in InSb quantum wells. InSb is an attractive material for this type of work due to its small electron effective mass (0.014 mo), high intrinsic electron mobility, ...
