The application of an electric field while growing carbon nanotubes with CVD can induce deformations in the SiO 2 substrate. The effect is attributed to field emission from the tubes and Marangoni convection in a small molten SiO 2 region underneath the tubes. Postgrowth deformation has been performed as well as large scale deformations using the collective effect of many field emitters. The porosity of one type of deformation is also examined and discussed. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
