“…Atomic H was found to reduce and stay intact with surfaces such as VO 2 (110) and vanadyl groups of V 2 O 3 (0001). 41 This agrees with our observations that atomic H reduces the surface by forming a stable OH group which could stay intact on the surface.…”

“…The most likely candidate is a H atom from the rest gas, given the high affinity of the vanadyl-terminated surface to form OH groups. 34 As V v O groups in direct contact with defects are more reactive than those inside a perfect layer, H adsorption will preferentially take place at those surface sites. The latter scenario is backed by the fact that modified vanadyls with unusual dI / dV signature sometimes hop to neighboring sites, as expected for the diffusive motion of an adsorbate.…”
