High temperature hydrogen annealing

WebThis study investigates the shape transformation of 4H-SiC microtrenches that occurs during high-temperature hydrogen annealing, which is used to improvegrowth on such prepared substrates. The trenches have micron-sized widths and depths and were annealedin hydrogen ambient at temperatures of 1400–1600 C for 30–3600s. http://www.c2mi.ca/wp-content/uploads/2024/02/White-paper_H2_Anneal_V02.pdf
