Device fabrication and dc electrical transport properties of barium manganite nanofibers (BMO-NFs)

Barium manganite nanofibers were synthesized using electrospinning technique. X-ray diffraction revealed the formation of single phase BaMnO3 nanofibers. Scanning electron microscopy revealed the formation of uniform composite and porous BaMnO3 nanofibers with an average diameter of ∼130 nm and <100 nm at 100 °C and 600 °C, respectively. Temperature dependent dc transport study of BMO-NFs device showed three distinct regions. The dominant conduction mechanism was space charge limited current with an exponential distribution of traps. The trap density was calculated to be 5.78 × 109 cm−3 using the cross-over voltage. These results provide new paradigm for developing nanofibers devices that may ultimately contribute to nanotechnology.
