Investigation of electrical conductivity (AC/DC) and dielectric properties of Se80Te15−xCd5Bix (x = 0, 5, 10) quaternary chalcogenide glass

Synthesis, structural, spectroscopic and electric/dielectric studies of a nanocrystalline Ni(ii) complex based on [(1,3-diphenyl-1H-pyrazol-4-yl)methylene]thiocarbonohydrazide

“…The frequency dependence of ac conductivity σ ac could be explained by the following equation: 62–64 σ ac = constant × (2π f ) S …”

“…10) revealed enhanced hopping of the charge carriers between the sides of the potential barrier with increasing applied frequency. 59,61 The frequency dependence of ac conductivity s ac could be explained by the following equation: [62][63][64]…”

Study of conduction mechanisms of InSeSb nano-chalcogenide alloys

“…where λ is a dimensionless quantity ( ≈18), α is the coefficient of exponential decay {exp(−αR)} of the wavefunction of localized states (α ≈ 0.124 Å −1 ) [22,49], k B is the Boltzmann constant and N(E F ) is the density of localized states at the Fermi level. The equation (5) states the relationship between conductivity and temperature for Mott's conduction process which Variation of ln(σ(T)√T) against T 1/4 for In 0.1 Se 0.9−x Sbx (x = 0, 0.04, 0.08 and 0.12) system in the temperature range of 295-318 K.…”
