Abstract

Raman spectroscopy is commonly used as a standard quality analysis technique for graphene characterization since it allows unambiguous, high-throughput, nondestructive identification of the number of graphene layers. It also allows to qualify defect, doping, strain, disorder and chemical modifications levels, as well as to locate grain boundaries of graphene. Many of these quality parameters need to be monitored during process and/or

Abstract

Graphene, a 2D sp²-hybridized carbon sheet with one-atom thickness, has attracted increasing attention in recent years because of its unique structure and special properties. Recently several research publications have described the synthesis of 3D CVD graphene continuous networks^1,2 grown on Ni foam substrates and their utilization for various novel products and application developments such as high sensitive gas sensor³, electrode or electrode additive for solar cells⁴ and ultra capacitors.⁵

Abstract

Continuous interest in Graphene materials has been recently reinforced with the awarding of the Nobel Prize in Physics, 2010. Graphene materials are considered for use in a wide variety of practical applications including electronics, solar cells, MEMS and NEMS, as well as chemical and biological sensors. Our joined team has successfully grown graphene films on Ni and Cu using Chemical Vapor
