Behind the research

We are a junior research group at the Institute of Energy Materials and Devices (IMD-1) of Forschungszentrum Jülich. We want to understand how grain boundaries and internal interfaces control the behavior of structural and energy materials - and how their properties differ from those of the bulk.

Our team combines backgrounds in materials science, physics, and engineering. Students join through Bachelor, Master, and PhD projects that pair advanced electron microscopy at the Ernst Ruska-Centre with small-scale mechanical testing and materials synthesis.

Junior Research Group Leader

Nicolas J. Peter leads a junior research group at the Institute of Energy Materials and Devices (IMD-1) of Forschungszentrum Jülich. He studied materials science at Saarland University and received his doctorate from Ruhr-Universität Bochum for work carried out at the Max-Planck-Institut für Eisenforschung (now MPI for Sustainable Materials) in the department of Gerhard Dehm.

His research combines atomic-resolution scanning transmission electron microscopy and spectroscopy with micro- and nanomechanics to understand grain boundaries and internal interfaces in structural and energy materials - from segregation and grain boundary complexions to in-situ deformation, heating, and biasing experiments.
