These additional references and the necessary callouts should have been located within the paper as detailed below.
Reference 19 should appear on p. 2, after the seventh sentence of Sec. 2.1 as follows:
Ion energy measurements were made using a versatile multigrid retarding-field ion energy analyzer (IEA) for the determination of ion energy distribution functions (IEDFs) in vacuum processing systems.19
Reference 20 should appear on p. 2, after the eighth sentence of Sec. 2.1 as follows:
Reference 21 should be called out on p. 7, before the first sentence of the last paragraph of Sec. 4, and on p. 8, after the third and last sentences of the first paragraph of Sec. 5, and after the captions of Figs. 16 and 17, respectively, as follows:
