We report a technique for the design of high‐density catalyst nanoparticles (NPs) which allow the growth of highly packed forests of carbon nanotubes (CNTs). The technique consists of cycles of deposition and annealing of thin metal films, followed by NP immobilisation. This allows a CNT areal density of at least 10 13 cm −2 .
