(abstract)

Hydrogen dynamics in the nanoscale region of VO2 was investigated by muon spin rotation/relaxation ($$SR) technique. Positively charged muon acts as a light radioisotope of proton and can be used as a probe to explore the inside of materials from an atomic perspective. By analyzing the muon hopping rate and the spatial distribution of the 51V nuclear magnetic moments, we have identified two types of diffusion paths in VO2 (via oxygen-muon bonds or defects) and the potential of a high diffusion coefficient in the 10^−10 cm2/s range at ambient temperature. Our results provide valuable information for developing hydrogen-driven VO2-related electronic devices.
