The Materials Map is an open tool for improving networking and interdisciplinary exchange within materials research. It enables cross-database search for cooperation and network partners and discovering of the research landscape.

The dashboard provides detailed information about the selected scientist, e.g. publications. The dashboard can be filtered and shows the relationship to co-authors in different diagrams. In addition, a link is provided to find contact information.

Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Abstract

Non-polar a-plane GaN films grown by hydride vapor phase epitaxy were studied by means of transmission electron microscopy in order to elucidate defect formation mechanisms. The typical defects found were 11 basal plane stacking faults and Frank-Shockley partials. Moreover, prismatic stacking faults could be identified, which were lying on the (01-10) and (11-23) planes forming closed domains and occasionally containing rectangular voids, which were found to be nanopipes originating at the interface with the substrate. The energetics of the partial dislocation formation mechanism is discussed.
