2013/1/15· Silicon carbide (SiC) has been around for more than 100 years as an industrial material and has found wide and varied appliions because of its unique electrical and thermal properties. In recent years there has been increased attention to SiC as a viable material for biomedical appliions. Of particular interest in this review is its potential for appliion as a biotransducer in
A comprehensive systematic method for chemical vapor deposition modeling consisting of seven well-defined steps is presented. The method is general in the sense that it is not adapted to a certain type of chemistry or reactor configuration. The method is demonstrated using silicon carbide (SiC) as a model system, with accurate matching to measured data without tuning of the model. We
