A facile chemical vapor deposition‐based method for the texturing of substrate‐supported iron‐filled multiwalled carbon nanotube arrays is reported. The method is based on the interplay of temperature gradients and modulated vapor flow that produces annular height variation and a vertical‐array‐to‐spherulitic morphological transformation in experimental conditions, which result in uniform, close‐packed arrays of constant height in an unmodulated vapor flow. These observations are proposed to result from creation of stationary cells of feedstock vapor above the growth front.
