Switching the wires : p‐Type α‐Fe 2 O 3 nanowires with ordered oxygen vacancies were synthesized without additional annealing. After a process of annealing in a reductive ambient, a p‐type to n‐type transition was achieved in a nanowire device (see graph and image). The observation of a p–n transition suggests potential applications for these nanowires in future nanodevice technologies.
