  • The locally defined growth of carbon nanofibers with lambda shape in an open flame process is demonstrated. Via the growth time, the geometry of the structures can be tailored to a Λ‐ or λ‐type shape. Microchannel cantilever spotting and dip‐pen nanolithography are utilized for the deposition of catalytic salt NiCl2 · 6H2O for locally controlled growth of lambda‐shaped carbon nanofibers. Rigorous downscaling reveals a critical catalytic salt volume of 0.033 µm³, resulting in exactly one lambda‐shaped carbon nanofiber at a highly predefined position. An empirical model explains the observed growth process.
