The relations between chemical vapor deposition (CVD) parameters and the resultant pyrolytic carbon microstructures have been examined for matrix deposition in fibrous carbon substrates. The parameters considered are temperature (1200-145O"C), pressure (20-630 Torr), C/H ratio (l/4-1/14), total flow
OH 44135) . Measurements of resistance between 4 and 70 Kelvin reveal maxima as a function of temperature in fixed fields between 0 and 10.6 Tesla (106 kc). The maxima grow with field, and move up in temperature. Possible interpretations are proposed. tvisiting Scientist.
## Vapor grown carbon fibers; light paraffins; liquid pulse injection technique Vapor grown carbon fibers (VGCFs) were successfully produced at high growth rates using light paraffins as the carbon source. VGCFs grow in the axial direction through the catalytic action of ultra-fine metal particle
