Summary: Spokes are observed in the magnetized region of DC magnetron sputtering, HiPIMS, and other discharges. Measuring spokes quantitatively is difficult due to their high velocities. However, synchronizing Langmuir probe measurements with the movement of spokes in DCMS allows for obtaining the probe current-voltage characteristics without averaging out the spoke influence. The plasma parameter modulation caused by spokes is revealed through the evaluation of the I-V curves. The comparison between DCMS and HiPIMS spokes shows that the modulation strength is weaker in HiPIMS due to the higher collision frequency of electrons.

Summary: By doping a sputtering target with atoms of higher atomic mass, the sputtering yield amplification (SYA) phenomenon can be achieved, promoting a higher ejection of target atoms. A new method of generating the SYA phenomenon without the need for expensive and complex deposition systems was presented by increasing working pressure and adding dopant elements. Experimental results showed that the percentage of SYA depends on the number of redeposited dopant atoms and their depth distribution on the target surface.

Summary: Strontium zinc phosphate glasses containing neodymium ions were prepared. The presence of phosphate groups in the Q2 mode overlapping with Zn-O and Sr-O bonds was observed in the current glasses. The replacement of SrO with Nd2O3 increased the glass density. The optical transition was found to be an indirect transition with varying values. The absorption spectra showed distinct peaks due to the presence of Nd2O3, and the emission spectra suggested possible emission of NIR lasers at specific wavelengths.

Summary: A measurement method that is not affected by RF fluctuations has been proposed for obtaining electron temperature and plasma density in RF discharges. By measuring the self-bias voltage and fundamental frequency current of a floating planar probe, the electron temperature and plasma density can be determined. Compared to conventional methods, such as electron energy probability function and floating harmonic method, our method is less influenced by RF fluctuations. The results from our method agree well with those from the floating harmonic method under different RF powers and gas pressures.

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.
