A study of the optical transmission properties of the polymer HPG.
(2000)
Hydroxypropyl Guar (HPG) is a polymer used extensively in the petroleum industry for fracturing oil and gas wells. Understanding the transmission of electromagnetic (EM) radiation in these fluids plays an essential role ...
IV-VI semiconductor structures for laser fabrication of silicon.
(1998)
This dissertation describes experiments undertaken to develop techniques required to develop IV-VI lasers grown on silicon. A review of the IV-VI materials system, diode laser structures, recent IV-VI laser results, epitaxial ...
Molecular beam epitaxial growth and characterization of europium-doped calcium fluoride and fabrication of visible electroluminescent devices on silicon.
(1998)
An indirect band-gap precludes the possibility of efficient luminescence from Si. The widespread use of Si in electronics and rapid advances in Si device processing and design justifies the search for Si-based light emitters ...
Characterization of IV-VI semiconductor materials and devices by Fourier transform infrared spectroscopy.
(1999)
Emissions from a commercial IV-VI semiconductor PbEuSe diode laser were also obtained using a modular type MR spectrometer. The laser exhibits wide (up to 4 cm-1) continuous wave, single-mode tuning regions between 90 K ...
Carbon Nanotube Enhanced Lithium Ion Composite Cathodes
(2014-08-13)
Batteries are sought that can deliver high energy density and high power density over thousands of cycles, with minimum environmental impact and cost. Invariably no one material can achieve all of these requirements. Lithium ...
GROWTH OF WIDE BANDGAP SEMICONDUCTORS USING PULSED ELECTRON BEAM DEPOSITION (PED) PROCESS
(2015)
Wide bandgap materials hold a great potential in solid state lighting, power electronics, and radio frequency (RF) device applications. The cumulative market for all these applications is forecasted to be approximately $75 ...
