(1) We developed a surrogate model for graphene-based conductor materials using Gaussian process regression.
The material of interest is a stack of layers of graphene flakes.
The results of previously performed nodal analysis have been used to obtain a model for calculating in-plane and out-of-plane conductivities much faster.
We present results depending on various material parameters like flake size, packing density, flake conductivity, and inter-layer conductivity.
(2) Recently the Plattform MaterialDigital (www.materialdigital.de) started to facilitate digital twins in material science, i.e. the creation of an ontology-based data storage for the digital representation of (new) materials and their properties in relation to key processing steps.
We participate in this and present an ontology specialized to graphene-based conductor materials, which we fill with simulation data as well as laboratory data.
