We have developed a selective growth technique of carbon nanotubes (CNTs) on stainless steel (SS) using a patterned amorphous silicon (a‐Si) buffer layer by inductively coupled plasma enhanced chemical vapor deposition (ICP‐CVD). The deposition of a 30 nm thick a‐Si on SS gives a uniform growth of multi‐walled CNTs, aligned vertically to the substrate with an average diameter of 70 ∼ 200 nm and a length of ∼1 μm. The CNTs exhibited a turn‐on field of 0.9 V/μm, a current density of 1 mA/cm 2 at 3.5 V/μm and uniform electron emission
