Electrical conduction mechanism and transport properties of LiCrP2O7 compound

Impedance spectroscopic investigation on phase transition and electrical conduction mechanism of the new inorganic-organic complex: (C6H9N2)2HgCl4 (I), (C6H9N2)2(Hg0.75Cd0.25)Cl4 (II) and (C6H9N2)2(Hg0.12Zn0.88)Cl4 (III)

“…Values of the parameters used in the fitting procedure for sample under investigation are listed in Table 1. We remark the augmentation of both parameters α -1 and N with frequency, which is in accord with the literature [29].…”

The investigation of dielectric properties and ac conductivity of new ceramic diphosphate Ag 0.6 Na 0.4 FeP 2 O 7 using impedance spectroscopy method

“…-The overlapping large-polaron tunneling (OLPT) model, if s decreases at first, reaching a minimum and increases thereafter with increase temperature [5].…”

Investigation of annealing effects on the physical properties of Ni0.6Zn0.4Fe1.5Al0.5O4 ferrite

“…In contrast, for Ni1200, 's' decreased, reached a minimum and then increased; thus, overlapping large polaron tunneling (OLPT) ensured conduction for this latter sample. 52 For the Ni600 and Ni900 samples, the values of 's' exceeded 1, while for the Ni1200 sample, the values of 's' were lower than 1. Thus, for Ni600 and Ni900, jump of the charge carriers occurred between neighboring sites, whereas for Ni1200, the electron jump occurred between two distant sites.…”
