The electrical transport properties of hydrothermally synthesized V 2 O 5 nanowires were investigated by impedance spectroscopy at room temperature in the frequency range of 1 Hz–1 MHz. The structural and morphological analyses confirm the single crystalline orthorhombic nature of the nanowires. The complex impedance plane plot showed two overlapping semicircles with dominating low frequency arc. The resistance from the oxygen vacancies and oxygen stoichiometric V 2 O 5 NWs regions contribute to the overall transport behavior of NWs. The normalized functions (Z///Z max//and M///M max//) suggests that the long range movements of the charge carriers are dominant at 100 Hz. The tangent loss (tan δ) was observed in accordance with the impedance plane plot. The ac conductivity σ ac showed substantial increase from 1× 10− 6–3× 10− 5 (S/cm 2) in the frequency range of 5× 10 3–10 5 Hz attributing to a large number of charge carriers available for conduction by hopping.
