Identification of iron oxide phases in thin films grown on Al2

Webb15 maj 2024 · If available, we combine these data with experimental Raman spectra and relations of vibrational modes with the atomic arrangements and motions in crystals. Further, we employ arc sputtering to produce vanadium oxide films, including α and β-vanadium, V 14 O 6 , VO, V 2 O 3 , V 3 O 5 , several phases of VO 2 , V 6 O 13 , V 3 O 7 , … Webb7 dec. 2010 · In the present work, near-resonance enhancement of the Raman spectra was investigated for the iron oxide and iron oxyhydroxide compounds previously reported to … WebbA Raman peak at 603 cm –1 appeared for all the four samples at OER-relevant potentials, ≥1.62 V vs RHE. This peak was identified as the Cu–O stretching vibration band of a Cu III oxide, a metastable species whose existence is dependent on the applied potential. powerapps onselect 関数
