Summary: A material system composed of cadmium sulfide and chromium atoms was studied to examine the influence of chromium concentration on the properties of a precursor layer of CdS. The study found that the transmission spectra increased for all analyzed chromium concentrations. X-ray diffractograms showed that CdS exhibited a mixture of orthorhombic, hexagonal, and cubic phases. The addition of chromium resulted in changes in diffractogram peaks and an anomalous shift in the pattern of CdS. The calculated resistivities remained constant at 4.5 x 10(6) ohm cm, and the bandgap values were approximately 2.43-2.44 eV. The addition of chromium at different concentrations also led to changes in surface morphology, as observed in SEM images.

Summary: This study investigates the AlN nucleation layer issue in GaN high frequency telecommunication and power switching systems fabricated after heteroepitaxy on Silicon or Silicon Carbide. It is shown that using 3C-SiC as an intermediate layer can significantly decrease RF propagation losses. Measurements and analyses demonstrate that dopant diffusion into the 3C-SiC pseudo-substrate is confined beneath the interface, and a slightly conductive zone is present beneath the AlN/3C-SiC interface, explaining the low propagation losses obtained for the devices. This work highlights the importance and efficiency of the 3C-SiC intermediate layer as a pseudo-substrate.
