By using a variety of experimental techniques, we were able to reveal the presence of few percent of well‐ordered graphene islands mixed to disordered carbon, isolated carbon tubes, and flakes. The sample were synthesized on a metallic TiN film using catalytic chemical vapor deposition and characterized by scanning electron microscopy, Raman spectroscopy, and K‐resolved inverse photoemission spectroscopy. Because of the metallic TiN support and the presence of well‐ordered one or two layers graphene islands, the so grown carbon nanostructures (CNs) can be used in many applications. Our results indicate that a multi‐techniques approach is fundamental to fully characterize CNs.
