Query: Effect of 50 MeV Li3+ irradiation on structural and electrical
  properties of Mn doped ZnO   The present work aims to study the effect of ion irradiation on structural
and electrical properties and their correlation with the defects in Zn1-xMnxO
type system. Zn1-xMnxO (x = 0.02, 0.04) samples have been synthesized by
solid-state reaction method and have been irradiated with 50 MeV Li3+ ions. The
concomitant changes have been probed by x-ray diffraction (XRD), temperature
dependent electrical resistivity and positron annihilation lifetime (PAL)
spectroscopy. XRD result shows single phase wurtzite structure for
Zn0.98Mn0.02O, whereas for Zn0.96Mn0.04O sample an impurity phase has been
found apart from the usual peaks of ZnO. Ion irradiation dissolves this
impurity peak. Grain size of the samples found to be uniform. For
Zn0.98Mn0.02O, the observed sharp decrease in room temperature resistivity
(RhoRT) with irradiation is consistent with the lowering of FWHM of the XRD
peaks. However for Zn0.96Mn0.04O, RhoRT decreases for initial fluence but
increases for further increase of fluence. All the irradiated Zn0.98Mn0.02O
samples show metal-semiconductor transition in temperature dependent
resistivity measurement at low temperature. But all the irradiated
Zn0.96Mn0.04O samples show semiconducting nature in the whole range of
temperature. Results of room temperature resistivity, XRD and PAL measurements
are consistent with each other.
