Terahertz spectroscopy of semiconductor nanostructures
Electromagnetic waves centered at a frequency of 1 terahertz (THz) lie between the realms of photonics and electronics. Only recently have techniques been established to generate and detect electromagnetic waves in this ...
Nanostructured photovoltaic devices for next generation solar cell
As the search for alternative sources of energy other than petroleum continues to expand, solar energy conversion has already been identified as one of the most promising technologies. In the past few years there has been ...
Aerosol spray pyrolysis & solution phase synthesis of nanostructures
This dissertation focuses on the synthesis of nanomaterials by both solution phase and gas phase methods. By the solution phase method, we demonstrate the synthesis of Au/CdS binary hybrid nanoparticles and the Au-induced ...
Solution phase synthesis of multicomponent and anisotropic nanostructures
The ability to explore additional dimensions besides particle size to tune the properties of nanomaterials has important implications for the development of new materials, and may provide a basis for the development of new ...
Design, Growth, and Characterization of Mid Infrared and Terahertz Detectors Based on Nanostructures
In the first part of the dissertation, I present the design, growth, and characterization a multi-color quantum well infrared photodetecor (QWIP). The QWIP is based on GaAs/Al0.2Ga0.8As coupled double-quantum-well structure ...
Vertically Aligned Nanostructured Arrays of Inorganic Materials: Synthesis, Distinctive Physical Phenomena, and Device Integration
The manifestation of novel physical phenomena upon scaling materials to finite size has inspired new device concepts that take advantage of the distinctive electrical, mechanical, and optical, properties of nanostructures. ...
