摘要: Abstract A comprehensive analysis of operating parameters Addon RF nitrogen plasma source was made in order to determine how a ratio different active species depends on the such as supplied power and flow. We show that output signal optical sensor measures intensity light emitted by is direct measure amount available for growth. Results emission spectroscopy measurements growth kinetics excited metastable molecules are mainly contributing GaN under Ga-rich conditions. procedure presented allowing find an optimal conditions cell high-quality Under these flux contains maximum minimal ionic atomic minimize lattice damage, even at high rates.
