Investigation of structural, dielectric, impedance and leakage current behaviour of green phase of yttrium barium copper oxide:Y2BaCuO5

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

“…9 presents the plot of ln σ ac versus 1000/ T at different frequencies. Clearly, σ ac increased with increasing temperature up to 323.5 K, obeying the Arrhenius relation: 56–58 where Δ E ac is the ac activation energy. The increase in σ ac with increasing temperature could be due to the enhanced thermal activation of the electron drift velocity.…”

“…9 presents the plot of ln s ac versus 1000/T at different frequencies. Clearly, s ac increased with increasing temperature up to 323.5 K, obeying the Arrhenius relation: [56][57][58]…”
