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 BaMn03 nanofibers. Scanning electron microscopy revealed the formation of uniform composite and porous BaMn03 nanofibers with an average diameter of similar to 130 nm and <100 nm at 100 degrees C and 600 degrees 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 x 10(9) cm(-3) using the cross-over voltage. These results provide new paradigm for developing nanofibers devices that may ultimately contribute to nanotechnology. (C) 2014 Elsevier B.V. All rights reserved.
