p-Type α-Fe2O3 Nanowires and their n-Type Transition in a Reductive Ambient

Switching the wires: p‐Type α‐Fe2O3 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 s...

Zusammenfassung:Switching the wires: p‐Type α‐Fe2O3 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.
