Title of dissertation: ELECTRON TRANSPORT SIMULATIONS AND BAND STRUCTURE CALCULATIONS OF NEW MATERIALS FOR ELECTRONICS: SILICON CARBIDE AND CARBON NANOTUBES. Gary Pennington, Doctor of Philosophy, 2003 Dissertation directed by: Professor Neil Goldsman Department of Electrical Engineering Silicon carbide (SiC) and carbon nanotubes (CNTs) are two materials which have promising potential in electr...

Polymer-derived ceramic (PDC) process is an attractive technique that has high yield. This versatile method allows for fabrication of porous carbon nanotube (CNT)/ silicon carbide (SiC) hybrid materials important temperature structural applications. Although several forms CNT assemblies have been used with the PDC approach, fabricated CNT/ceramic nanocomposites were either one or two dimensiona...

Substitution reactions between multiwalled carbon nanotubes and silicon monoxide vapour have been investigated using transmission electron microscopy. Different reactions occurred inside the multiwalled nanotubes and on the nanotube external surfaces, resulting in the formation of silicon carbide nanowires with a core–shell structure. The substitution reaction process and end products are stron...

Multi-walled as well as single-walled carbon nanotubes are conveniently prepared by the pyrolysis of organometallic precursors, such as metallocenes and phthalocyanines, in a reducing atmosphere. Pyrolysis of organometallics alone or in mixture with hydrocarbons also yields aligned nanotube bundles with useful field emission properties. By pyrolyzing organometallics in the presence of thiophene...

Abstract Since much attention has been paid to the targeted drug delivery system, using molecular dynamics simulation, present work devoted clarify potential of silicon carbide nanotubes (SiCNTs) as a new carrier for three common anti-cancer drugs temozolomide, carmustine, and cisplatin. Three zigzag single-walled with different diameters, i.e. SiC(18,0), SiC(20,0), SiC(22,0), in pure decorated...
