Indium doped tin oxide submicrometre sized wires have been synthesized by thermal evaporation and characterized by field emission (FE) microscopy. The non-linear Fowler-Nordheim plot corresponds to the typical semiconducting behaviour of the emitter. The field enhancement factor has been estimated to be 29 900 cm-1 indicating that electron emission is due to the nanometric features of the emitter. A current density of the order of 6.36×103 A cm-2 with an applied electric field of 1×104 V μm-1 has been obtained. The long term FE current stability tested at the preset current level of 1 μA exhibits no severe fluctuations.
