Synthesis and study of different carbon nanomaterials diamond like carbon carbon nanoflakes and graphene thin films

Abstract

In this thesis different structures of carbon allotropes diamond like carbon carbon nanoflakes and single and multi layer graphene films are grown by hot filament chemical vapor deposition CVD method These structures were grown with varying different deposition parameters such as substrate temperature process pressure CH4 H2 gas flow rates deposition time and filament to substrate distance Graphene was also prepared by thermal reduction of graphene oxide at different annealing temperat
