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
