cm3/min. After the CNT growth time, the plasma was turned off, and the heater was cooled down slowly to prevent the CNT damage from the sudden change of temperature. 3 Results and discussion... that a single nano dot needs shorter NH3 etching time than a large area patterned one to grow CNTs as a single dot forms catalyst island already. 3) Different NH3 etching times are optimized for a bundle......
