Creator:: Reidy, Christopher F.
Abstract:: Several topics are presented in this dissertation, each of which has applications to solar cells and photodetectors. First, we discuss the growth of Cu10Te4S13, copper tellurium tetrahedrite. This material has interesting optical properties; it has a large joint density of states at the conduction band maximum and valence band minimum,...
Resource Type:: Dissertation
Full Text:: valence band minimum, which gives high absorption right at the band gap energy while remaining

Creator:: Hersh, Peter A.
Abstract:: The work presented here is focused on applying basic principles of solid-state chemistry to the study and development of new wide band-gap semiconductors and insulators for photovoltaic and electronic-device applications. Analysis of crystal structure, band structure, optical band gap, morphology and transport properties provides fundamental insight into materials performance as...

Full Text:: degree of Doctor of Philosophy in Chemistry presented on the 4th of October 2007 Title: Wide Band Gap

Creator:: Kykyneshi, Robert
Abstract:: Thin films of wide band-gap semiconductors are deposited by the pulsed laser deposition method. Optimal deposition parameters for the individual compounds are reported. A family of p-type BaCuQF (Q = S, Se, Te) ceramics with a layered crystalline structure is investigated for active and passive device applications. Epitaxial films of...
Resource Type:: Dissertation
Full Text:: transparent to visible light because of the low band gap. A wide, 3.1 eV or larger, band gap semiconductor

Creator:: Zakutayev, Andriy
Abstract:: BaCuChF (Ch = S, Se, Te) materials are chalcogen-based transparent conductors with wide optical band gaps (2.9 – 3.5 eV) and a high concentration of free holes (10¹⁸ – 10²⁰ cm⁻³) caused by the presence of copper vacancies. Chalcogen vacancies compensate copper vacancies in these materials, setting the Fermi level...
Resource Type:: Dissertation
Full Text:: wide-bandgap semiconductor or a very thin layer of metal. 2. Both contacts should be sufficiently
