Here, we report a systematic study on the CCVD synthesis of carbon nanotube forests on titaniumbased substrates. As a crucial issue, the effect of the presence of an insulating layer (alumina) on the growing forest was investigated. Other important parameters, such as the influence of water vapor or the Fe-Co catalyst ratio, and the incorporation of nitrogen into carbon nanotube were also studied during the synthesis. As-prepared CNT forests were characterized by various techniques: scanning and transmission electron microscopies, Raman spectroscopy, energy-dispersive X-ray spectroscopy, spectroscopic ellipsometry. date: 2019 type: Konferencia vagy workshop anyag type: NonPeerReviewed format: part language: hu identifier: http://acta.bibl.u-szeged.hu/64892/1/proceedings_of_isaep_2019_403-407.pdf identifier: Szabó Anna; Pápa Zsuzsanna; Gyulavári Tamás; Németh Krisztián; Nagy Diána; Hernádi Klára: Growth of CNT forests on titanium substrates : effect of catalyst ration and hydrogen on the incorporation of nitrogen into carbon nanotube structure.
