Abstract
Polycrystalline ZnO:Mn films have been deposited on Si substrates byusing ultrasonic spray pyrolysis methods. ZnO:Mn (3{\%}) films showhysteretic behaviors in the $I$-$V$ curves and these behaviors arerelated to charging and discharging of Mn-oxide nanoclusters. Theconditions for hysteresis to appear depend on the sizes of theformed Mn-oxide nanoclusters close to the electrode interfaces.
Keywords: ZnO:Mn, Hysteretic behaviors of $I$-$V$ curves
