Although carbon-nanofiber (CNFs) or nanotube growth and their applications are well documented, engineering their shape and their integration in a microsystem for successful applications is an important issue. We report on the synthesis of aligned CNFs (ACNFs) covered by metallic catalytic nanoclusters by a combination of different low-pressure deposition techniques based on high-density radio-frequency helicon plasmas. An image of a “bright-dress-shape” helicon plasma and of a synthesized ACNF coated by Pt nanoclusters is presented.
