| Abstract
| - We observed two long-range-ordering structures of oxygen vacancies, one in every tenth plane of (33̅0) and another in every fourth plane of (11̅2) in α-Fe2O3 nanowires and nanobelts synthesized under the same conditions. Interestingly, both types of oxygen-vacancy structures found in different nanowires have an equivalent ordering distance of 1.45 or 1.47 nm and were parallel to the growth direction of the nanowires and nanobelts. Lattice mismatch induced strain at the growth temperatures seems to justify the observed vacancy-ordering distance and may explain the reason for occurrence of such oxygen-vacancy ordering in various metal oxide nanowires grown from using both foils and catalyst clusters.
- Long-range ordering of oxygen vacancies in two different planes, every fourth of the (11̅2) plane or every tenth of the (33̅0) plane, with equivalent ordering distance are found in α-Fe2O3 nanowires and nanobelts.
