     in carbon nanotube (cnt) growth process via chemical vapor deposition (cvd) method, there are two distinct regimes based on growth temperatures, so called mass transfer controlled and surface reaction controlled regimes, which represent different type of behaviour in growth. operating in each regime has different characteristic that can influence on other operating condition effects on cnts growth. thus study of these regimes is important for better understanding of cnts growth; also it helps to control of other operating conditions effect on growing cnts. in this paper these two regimes is established and then relevant processes in reactor is studied in details. results show that cnts total production in mass transfer controlled regime has higher order and less sensitivity to the growth temperature compared to surface reaction controlled regime. also produced cnts in mass transfer controlled regime has less length uniformity compared to surface reaction controlled regime.
