Description
The DataSet contains the linear electrical properties of V2O5 nanorods which were measured by the impedance spectroscopy method. V2O5 nanorods were obtained by the sol-gel method. The information about xerogel powder synthesis is described in the Journal of Nanomaterials. The precursor powder was pressed into the disk-shaped pellets (12mm in diameter and 1mm in thickness) under a compacting pressure of 25 kN/cm2. The V2O5 nanorods are achieved by annealing the pellet at 923K for 10 h with a heating rate of 0.1 K/min and a cooling rate of 0.5K/min.
For the electrical measurements, gold electrodes were evaporated at the preheated and ground sample. Impedance measurements were carried out in the temperature range from 153 K to 423 K, in the frequency range from 10mHz to 1 MHz, and with the ac voltage of 0,1 Vrms with Concept 40 broadband dielectric spectrometer.
These results are part of a project defined in the Electrochimica Acta. In this paper, the information about samples and synthesis details are reported.
