The electrical characterisation process aims to determine the electrical properties of materials and conductive systems as part of the general transport properties of solids. .
The group is specialised in the parametric study of the electrical behaviour of materials and its interpretation when exposed to controlled steady electric and magnetic fields. The parameters include temperature (10 – 300 K), magnetic field (1.4 T), the composition and structure of the materials, as well as the geometry and topography of the samples under test and their electrical contacts.
The characterisation process is based on the online measurement of the electrical conductivity, the Hall Effect and the magnetoresistance of materials, according to the Van der Pauw and Wascher methodologies. .
The group has extensive experience in the characterisation of semiconductors, metals and semi-metals, as well as in the exploration of suitable theoretical models in order to further investigate and expand the methodologies of measurement of inhomogeneous and anisotropic materials. .
