Article Synopsis
- The study explores the complex interaction between plasmonic and magnetic effects in organic composite semiconductors, specifically in self-assembled Co-C nanocomposite films.
- It identifies a quantum plasmon in the Co-C films, particularly in the LF sample, characterized by an optical absorption peak at 1.5 eV and additional C-related absorption lines at higher energies.
- Increasing cobalt content enhances optical absorption intensity and shifts the plasmonic peak, indicating significant changes in the material's microscopic conditions and suggesting potential for spin polarization effects.
The microstructure of polar GaN layers, grown by upgraded high-temperature vapour phase epitaxy on [001]-oriented sapphire substrates, was studied by means of high-resolution X-ray diffraction and transmission electron microscopy. Systematic differences between reciprocal-space maps measured by X-ray diffraction and those which were simulated for different densities of threading dislocations revealed that threading dislocations are not the only microstructure defect in these GaN layers. Conventional dark-field transmission electron microscopy and convergent-beam electron diffraction detected vertical inversion domains as an additional microstructure feature.
