ABSTRACT
The field-emission (FE) properties of quasi-one-dimensional NbOx crystals are reported for the single needle geometry. Relatively stable FE currents in excess of 1 μA were measured after a careful conditioning in vacuum of 10-7 mbar. In all our experiments, the FE current originating from a few sites prevailed over the entire current range. This can be confirmed at least in the current range where the emission pattern could be observed on a high-resolution luminescent screen. © 2004 American Institute of Physics.
