Influence of Alumina Reaction Tube Impurities on the Oxidation of Chemically-Vapor-Deposited Silicon Carbide

constants for the oxidation of silicon in 99.8% pure alumina tubes were about a factor of 7 higher than other values reported in the literature. After changing to silica tubes, they found good agreement with the literature. In recent studies in this laboratory, it was

SOLID STATE PHYSICS PART II Optical Properties of Solids

The quantities ~n and ~k are collectively called the optical constants of the solid, where ~n is the index of refraction and ~k is the extinction coe–cient. (We use the tilde over the opticalconstants ~n and k are denoted by n and k). The extinction coe–cient k

Hydrogenated Silicon Carbide Thin Films Prepared with …

Structural, optical, and electrical properties of hydrogenated silicon carbide (SiC:H) films, deposited from silane (SiH 4) and methane (CH 4) gas mixture by HW-CVD method, were investigated. Film properties are carefully and systematically studied as function of deposition pressure which is varied between 200 mTorr and 500 mTorr.

Silicon carbide (SiC) is nearly as hard as diamond and is used as an abrasive. Silicon nitride is used in rotating bearing balls & rollers, cutting tools, engine moving & wear parts, turbine blades, vanes & buckets, metal tube forming rolls & dies, etc.

Relaxation and crystallization of amorphous silicon …

Optical spectroscopy in the visible (300–1100 nm) and in the infrared (400–4000cm −1) regions was used to monitor the relaxation and crystallization processes of pure amorphous silicon carbide (a-SiC) thin films upon annealing at temperatures between 200 and 1000 C.

Formation of Silicon Carbide Nanotubes and Nanowires …

One-dimensional silicon−carbon nanotubes and nanowires of various shapes and structures were synthesized via the reaction of silicon (produced by disproportionation reaction of SiO) with multiwalled carbon nanotubes (as templates) at different temperatures. A new type of multiwalled silicon carbide nanotube (SiCNT), with 3.5−4.5 Å interlayer spacings, was observed in addition to the
