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

<jats:title>ABSTRACT</jats:title><jats:p>Localized vibrational modes of carbon-hydrogen complexes in metalorganic chemical vapor deposition grown GaN on sapphire were studied using a Fourier-transform infrared spectroscopy technique. Three distinctive localized vibrational modes were observed around 2850, 2922, and 2959 cm<jats:sup>−1</jats:sup> for undoped, Si- and Mg-doped samples. These peaks are related to CH, CH<jats:sub>2</jats:sub>, and CH<jats:sub>3</jats:sub> defect complexes, respectively. It is also observed that the frequencies and intensities of the localized vibrational modes are sample dependent.</jats:p>
