CASE STUDY EURAMET - GRACE EMPIR PROJECT

02/08/2022

The study "Developing high-throughput methods to characterize graphene" published on January 20, 2022 on the website of EURAMET, European Association of National Metrology Institutes, presents the general context relating to the definition of metrologically validated and standardized methods for the electrical characterization of graphene, and it explores the interaction between the researchers of the GRACE project consortium with its industrial partners.

 

In particular, the document analyzes two aspects:

  • First: the impact of the GRACE project on the technological advancement produced by the industrial partner das-Nano (Spain), which has developed a commercial and compliant tool for contactless mapping of graphene electrical conductivity. It is an optical scanning technique called time-domain terahertz spectroscopy (TDS) [1].
  • Second: the interaction of the GRACE consortium with the International Electrotechnical Commission (IEC), aimed at the development and drafting of new standards dedicated to the electrical characterization of graphene for industrial purposes. In addition to the measurement standard with TDS technique (IEC TS 62607-06-25), other normative projects relating to the measurement of the electrical conductivity of graphene both with contact and non-contact techniques, have seen a contribution from the GRACE consortium (for more details, see [3], [4] and [5]).

 

The case study published by EURAMET highlights how GRACE has satisfied, among others, two important impact components expected by the pre-normative projects of EMPIR program: the "Impact on industrial and other user communities" component and the "Impact on relevant standards" component.
