Electrical Transport Measurements on the Alloy Sn₁-ₓCaₓSe

Creator:: Stahly, Joshua
Abstract:: Hall measurements can be made on the unstudied alloy, Sn₁-ₓCaₓSe to determine its electrical transport properties. The Sn₁-ₓCaₓSe samples were made by laser deposition into thin films and have a variable of calcium concentration x. These samples are approximately 250 nm in thickness, were grown at 366° C and are...

Room Temperature Seebeck Measurements on CuSc1-xMgxO2+y Transparent Conductive Thin Films

Creator:: Easley, Dara L.
Abstract:: A series of seven magnesium-doped copper scandium oxide films were made by radio frequency sputtering, and intercalated at various oxygen pressures to create different oxygen concentrations in each film. The objectives of this study were to verify the p-type nature of these transparent conductive thin films, to determine the correlation...

Zinc Tin Oxide Thin Films by Pulsed Laser Deposition for use in Transparent Thin-Film Transistors

Creator:: Osborne, James J.
Abstract:: Zinc tin oxide (ZTO) films deposited by pulsed laser deposition (PLD) are investigated as a channel layers for transparent thin-film transistors (TTFTs). Films are deposited on glass for characterization, and transistor channel layers are deposited onto aluminum oxide-titanium oxide/tin doped indium oxide/glass substrates (ATO/ITO/glass) to produce TTFTs. UV-visible spectroscopy on...

Crystallization and Growth of TiO2 Polymorphs from Pulsed Laser Deposited and RF-Sputtered, Amorphous Thin-Film Precursors

Creator:: Agirseven, Okan
Abstract:: TiO2 is a versatile wide bandgap transparent semiconducting oxide with three well known polymorphs: Anatase, Rutile and Brookite. These crystal structures are desired for many industrial applications mainly for their photocatalytic activity, oftentimes in thin-film form. Thin-film crystalline polymorphs of TiO2 are often made by physical vapor deposition on a...

Thermoelectric Characterization of SiliconWafers and Cu₁₂Sb₄S₁₃ Variant Thin Films

Creator:: Snyder, Rodney Austin
Abstract:: The Van der Pauw method for transport measurements of conductivity and carrier concentration were tested on indium-tin-oxide (ITO) films and silicon wafers, and then implemented on Cu10xAgxZn2Sb4S13 thin films. ITO was used as a test case for high temperature transport measurements because it a well characterized semi-metal. The mobility of...

Thermoelectric Properties of the HeterostructuralAlloy Sn_(1-x)Ca_(x)Se

Creator:: Forkner, MIchael
Abstract:: By alloying face centered cubic CaSe with orthorhombic SnSe, we created the heterostructural alloy Sn1-xCaxSe. The phase separated lms created with a high deposition temperature acted as highly crys- talline SnSe while the low deposition temperature lms acted as a mix of SnSe and CaSe. For the alloyed lms we...
