Measuring Graphene with a Benchtop Raman Spectrometer

Graphene and other carbon nanomaterials can be characterized with a small benchtop Raman spectrometer using the procedure described in this report

Introduction

Graphene, a two-dimensional allotrope of the element carbon, is a novel material with exceptional properties. It has the highest tensile strength of any material known to date, while simultaneously being a good electrical and thermal conductor. It is believed to be one of the key materials for the next generation of technology, which is visible in large public research projects such as the European Commission FET Flagship with a budget of 1 billion Euro.

Carbon nanomaterials such as graphene are extremely versatile and actively being included in applications in different industries:

  • to reinforce composite materials for automotive applications
  • to act as base material for micro-sensors probing both chemical (contamination, biomolecules) and physical (pressure, strain) properties
  • as an interface material for next-generation solar cells
  • activated graphene is used as electrode material in supercapacitors and lithium ion batteries
  • as material for flexible electronics like screens or smart wear
  • in optoelectronic devices that can be readily integrated with silicon photonic systems
