“…2,3) The CVD process is a growth method in which graphene is directly synthesized from carbon source gases, for example CH 4 , C 2 H 4 , and C 2 H 2 . The C-H bonding is too strong to be dissociated by only thermal energy, 4) so practicable graphene CVD methods can be divided into two types of CVD; one is the ''catalyst CVD'' using metal catalysts as the growth substrate, 2,3,[5][6][7][8][9] and the other is ''plasma-enhanced CVD''. 10,11) In particular, catalyst CVD is now widely used to obtain the large area and high quality graphene.…”

In this study, the behavior of carbon atoms in the annealing/cooling process of graphene/Cu(111) substrates is investigated using photoelectron spectroscopy and secondary ion mass spectroscopy. After the growth of graphene on Cu(111) surfaces, Cu2O was formed at the graphene/Cu interface during transportation through air atmosphere. The Cu2O layer completely disappeared by vacuum annealing at 500 °C. Graphene was decomposed and carbon atoms diffused into the Cu substrate by further elevation of annealing temperature to 950 °C. When the sample was cooled down, the carbon atoms did not segregate on the surface and remained in the Cu substrate. This result indicates the carbon atoms easily diffuse into Cu substrates in vacuum annealing while the amount of diffused carbon atoms in the thermal chemical vapor deposition (CVD) process is smaller, suggesting that the barrier layer, which prevents the diffusion of C atoms, exists on Cu surfaces in the graphene CVD growth.

“…Graphene is an attractive two-dimensional material consisting of carbon atoms arranged in a hexagonal lattice. [1][2][3] Various formation methods for graphene, such as mechanical exfoliation, 4) thermal decomposition of silicon carbon, 5) and chemical vapor deposition, 6,7) have been widely investigated. However, these methods are unfavorable for providing large-area graphene uniformly and require post-treatment.…”

The guidelines for a bottom-up approach of nanographene formation from pentacene using heated tungsten were investigated using a novel method called hot mesh deposition (HMD). In this method, a heated W mesh was set between a pentacene source and a quartz substrate. Pentacene molecules were decomposed by the heated W mesh. The generated pentacene-based decomposed precursors were then deposited on the quartz substrate. The pentacene dimer (peripentacene) was obtained from pentacene by HMD using two heated catalysts. As expected from the calculation with the density functional theory in the literature, it was confirmed that the pentacene dimer can be formed by a reaction between pentacene and 6,13-dihydropentacene. This technique can be applied to the formation of novel nanographene on various substrates without metal catalysts.

Jahrgang 26.Durch Pyrolyse kohlenstoff-haltiger Gase bei rd. 2000 OC und Abscheidung des dabei anfallenden elementaren Kohlenstoffs auf einem glatten Substrat erhiilt man einen Graphit, der einen hohen kristallographischen Orientierungsgrad besitzt und dessen physikalische Eigenschaften zum Teil stark richtungsabhangig sind. Durch thermische und mechanische Nachbehandlung lassen sich aus diesem Material massive Korper herstellen, denen praktisch die Eigenschaften von Graphit-Einkristallen zukommen. Die apparativen Verfahren und die thermodynamischen Voraussetzungen fiir die Kohlenstoff-Abscheidung aus der Gasphase werden beschrieben sowie einige Anwendungsmoglichkeiten fiir pyrolytischen Graphit aufgezeigt.
