Research paperExperimental GrowthExperimental CharacterizationActive nitrogen flux measurement during GaN growth based on the transmitted signal detected with a pyrometerMatteo Canciani, Stefano Vichi, Oksana Koplak, Sergio Bietti et al.2024·10.48550/arxiv.2412.15710·arXiv:2412.15710AbstractA novel approach for the measurement of the nitrogen active species generated by a plasma source in the molecular beam epitaxy environment is presented. The method analyzes variations in the optical signal measured by a pyrometer during two-step, gallium-rich and nitrogen-controlled growth modes, enabling quantitative measurement of the active species flux as a function of nitrogen gas flux and RF power.Read more
