Ercentage towards the SRO layers with decrease percentages, generating the gradual
Ercentage towards the SRO layers with decrease percentages, generating the gradual interfaces. However, the Si content material inside the SRN layer for MLA and MLB was about 49.1 0.2 and 50.0 0.four at. , respectively. It was previously shown that, in the course of the deposition of SRN, O atoms are incorporated into the single SRN films [36]. Moreover, the oxygen content material varied together with the RN value; the greater the RN value, the larger the O content material. A diffusion of N, Si and O atoms towards the SRN/SRO interface was also observed resulting from the thermal annealing forming an oxynitride layer (SiON) with progressively rising contents on the diverse components. Similar final results had been reported inside the literature for the formation of SiON in the interface of an SRN/SRO bilayer [37].Components 2021, 14, x FOR PEER Assessment Materials 2021, 14, 6582 Supplies 2021, 14, x FOR PEER REVIEW4 of 10 4 of 11 four ofFigure 1.
