Characterization of CdZnTe semiconductor for applications in advanced computed tomography
(2017)Cadmium zinc telluride (CdZnTe) is currently the only single crystalline semiconductor used in direct conversion gamma-cameras since CdZnTe can operate at room temperature, unlike other materials (e.g., germanium) that ... -
Computer simulation of functional materials for therapeutic ultrasound applications
(2015-01-13)Magnetic resonance imaging guided high intensity focused ultrasound is a potential non-invasive treatment which uses constructive interference patterns to concentrate ultrasound energy generated by a piezoelectric ... -
Dark Current modeling and characterization of amorphous lead oxide-based x-ray photoconductive devices for applications in medical imaging
(2022)High atomic number (Z) polycrystalline and amorphous photoconductors are currently being investigated to extend direct conversion X-ray detectors to real-time and high-energy lowdose applications. Amorphous lead oxide ... -
Development of Mid-IR Laser
(2025)We proposed and demonstrated a mid-IR fiber laser at 1925 nm using a thulium-doped fiber as the gain medium. The designed laser needs lower pump power compared to that previously reported. The developed laser is compact ... -
Fabrication, characterization and electrochemical studies of nickel and nickel-based materials
(2017)Nickel is a naturally abundant transition metal and is very cost effective. This, along with mechanical and magnetic characteristics, and good catalytic activity in different applications, has made it an interesting non-noble ... -
Formation and nanoscale characterization of self-assembled molecular structures on Au(111) and Ag(111) surfaces
(2024)The growing interests in nanomaterials stem from remarkable properties arising from reduced dimensionality. On-surface synthesis utilizes surface/nanoscale science techniques to design and make nanomaterials through a ... -
Lead oxide (PbO) for direct conversion detectors
(2017)There is great interest in the utilization of non-crystalline photoconductors for direct conversion medical X-ray imaging detectors. Lead Oxide (PbO) is one of the most promising candidates for application in general ... -
Microscopic modeling of high-field charge transport in amorphous selenium
(2014-01-22)Avalanche multiplication of charge carriers as a result of successive impact ionization has led to the development of solid state avalanche photo-detectors. Crystalline based avalanche photodiodes have found a variety of ... -
Photonic sensor based on surface-enhanced raman scattering for the detection of trace chemicals
(2025)The research presented in this thesis describes the development of a three-dimensional (3D) tapered optical fiber-based surface-enhanced Raman scattering (SERS) sensor for detecting trace chemicals. The developed system ... -
Plasmonic nanostructure on a tapered fiber for chemical detection
(2017)A simple, cost effective technique to manufacture plasmonic nanostructures as a Surface Enhanced Raman Spectroscopy (SERS) substrate was investigated. The plasmonic structure of gold nanorods was developed on the surface ... -
S U (3) Squeezing: quantum and semiclassical evolutions
(2013-02-03)In this thesis we describe a squeezing for SU(3) systems and compare squeezing in the phase space in the semiclassical approximation with squeezing obtained by the full quantum mechanical calculation. We show that the ... -
Synthesis and Electrochemical Studies of Titanium Dioxide Based Nanostructured Catalysts for Environmental Applications
(2016)Nanomaterials are playing an increasingly important role toward addressing emerging environmental challenges. Heterogeneous catalysis is the best option available for the elimination of environmentally incompatible compounds ... -
Tweezing and Manipulating Nanomaterials on Tapered Optical Fiber to Develop SurfaceEnhanced Raman Spectroscopy (SERS) Substrate
(2020)A compact and cost-effective fiber-based probe was manufactured for the detection of chemicals at low concentrations using Surface-Enhanced Raman Spectroscopy (SERS). Multi-mode optical fiber was tapered with a dynamic ...
