“…We demonstrated that the thickness of graphene, and the width of graphene nano-ribbons were controlled precisely by adjusting the reaction temperature, exposure time of deposition gases and choosing the substrate [8]: Depending on the interlayer interactions between graphene and the substrate, three different configurations were known: 1) On Pt (111), the crystallographic orientations of the growing graphene does not align with those of the substrate lattices because of the weak interlayer interaction [9]. 2) On TiC (111), ZrC (111), Ni (100), Ni (755) and Pd (111), the incommensurate epitaxial sheets grew because of the strong interlayer * Corresponding author: odagen@ruri.waseda.jp interaction; there are many extra diffraction spots in the low-energy electron diffraction (LEED) patterns owing to the multiple diffraction with two different periodicity [10][11][12].…”

Nanocrystalline diamond films have attracted considerable attention because they have a low coefficient of friction and a low electron emission threshold voltage. In this paper, the author reviews the plasma-enhanced chemical vapor deposition (PE-CVD) of nanocrystalline diamond and mainly focuses on the growth of nanocrystalline diamond by low-pressure PE-CVD. Nanocrystalline diamond particles of 200-700 nm diameter have been prepared in a 13.56 MHz low-pressure inductively coupled CH 4 /CO/H 2 plasma. The bonding state of carbon atoms was investigated by ultraviolet-excited Raman spectroscopy. Electron energy loss spectroscopy identified sp 2 -bonded carbons around the 20-50 nm subgrains of nanocrystalline diamond particles. Plasma diagnostics using a Langmuir probe and the comparison with plasma simulation are also reviewed. The electron energy distribution functions are discussed by considering different inelastic interaction channels between electrons and heavy particles in a molecular CH 4 /H 2 plasma. r

Graphene-the wonder material has attracted a great deal of attention from varied fields of condensed matter physics, materials science and chemistry in recent times. Its 2D atomic layer structure and unique electronic band structure makes it attractive for many applications. Its high carrier mobility, high electrical and thermal conductivity make it an exciting material. However, its applicability cannot be effectively realised unless facile techniques to synthesize high quality, large area graphene are developed in a cost effective way. Besides that a great deal of effort is required to develop techniques for modifying and opening its band structure so as to make it a potential replacement for silicon in future electronics. Considerable research has been carried out for synthesizing graphene and related materials by a variety of processes and at the same time a great deal of work has also taken place for manipulating and opening its electronic band structure. This review summarizes recent developments in the synthesis methods for graphene. It also summarizes the developments in graphene nanoribbon synthesis and methods to open band gap in graphene, in addition to pointing out a direction for future research and developments.
