Figure Legend:
Schematic representations of the TB-CVD system. (a) Schematic depicting the physical TB-CVD system. Purge, carrier, and precursor gases are metered into a three-stage tube furnace consisting of temperature-controlled heaters. Carbon is deposited on the templates, which are positioned in the center of the heated region. (b) Schematic depicting the geometric features and segments of the tube furnace and placement of the boat and templates. Segments B–D represent the heated region of the tube furnace.
