摘要: The electrical transport properties of hydrothermally synthesized V2O5 nanowires were investigated by impedance spectroscopy at room temperature in the frequency range 1 Hze1 MHz. structural and morphological analyses confirm single crystalline orthorhombic nature nanowires. complex plane plot showed two overlapping semicircles with dominating low arc. resistance from oxygen vacancies stoichiometric NWs regions contribute to overall behavior NWs. normalized functions (Z == =Z max M =M max) suggests that long movements charge carriers are dominant 100 Hz. tangent loss (tan d )w as observed accordance plot. ac conductivity sac substantial increase � 10 6 e3 5 (S/cm 2 ) 3 e10 Hz attributing a large number available for conduction hopping.
