| 12 | + complex oxides offers a rich platform to explore fascinating physical |
| 13 | + phenomena like helical edge states, broken-symmetry phases, and giant |
| 14 | + magnetoresistance. While current research primarily focuses on the |
| 15 | + influence of complex oxides on layered 2D materials, the |
| 16 | + reverse{\textemdash}how layered 2D materials affect complex |
| 17 | + oxides{\textemdash}remains largely unexplored. Here, we examined the |
| 18 | + impact of graphene layers on the formation of oxygen vacancies in |
| 19 | + SrTiO3 (STO) during high-temperature annealing. Our findings, |
| 20 | + supported by Raman spectroscopy and x-ray photoelectron spectroscopy, |
| 21 | + indicate that increasing the number of graphene layers progressively |
| 22 | + leads to a reduced oxygen vacancy content in STO, demonstrating the |
| 23 | + efficacy of graphene in modulating oxygen vacancy formation in bulk |
| 24 | + STO. Additionally, using photoluminescence, we showed that graphene |
| 25 | + layers can tune the in-gap states induced by oxygen vacancies in STO. |
| 26 | + Our first principal calculations further revealed that graphene layers |
| 27 | + increase the energy barrier for the outward diffusion of oxygen atoms, |
| 28 | + thereby inhibiting the formation of oxygen vacancies in STO. These |
| 29 | + results highlight a new route for tailoring the physical properties of |
| 30 | + complex oxides by engineering the interface with layered 2D materials.}, |
