Leakage Current Characterization of BaTi2O5 Nanowires

Single-crystalline BaTi2O5 nanowires were synthesized by a simple molten salt method, using BaC2O4•H2O and TiO2 powders as precursors. Electrical characterization was conducted with the as-synthesized BaTi2O5 nanowires. The current-time data of the nanowires obeyed the Curie-von Schweidler law. Steady-state I-V curve was obtained at room temperature from current-time data and it revealed that the leakage current of BaTi2O5 nanowires obeyed the ohmic law under low voltage, and obeyed the space-charge limited current (SCLC) law under higher voltage. The conductivity value of the BaTi2O5 nanowires is 2*10-6 S/cm.
