Electrical conductivity of barium titanate single crystals at high temperatureMonte Carlosimulationadsorptionpotential barriersElectrical conductivity of BaTiO3 single crystals is studied by means of AC impedance measurements on a wide range of temperature up to the melting point ( 1550 掳C). This work ...
The conductivity, Seebeck coefficient and Curie point have been measured in reduced crystals of barium titanate. The results have been interpreted in terms of a polaron hopping model, leading to an estimated mobility of 5×10 4 cm 2 V 1 sec 1 at 300° K, and an activation energy of ...
The electrical conductivity in ferrite has been attributed to electron hopping between the two valence states of iron, at crystallographically equivalent sites. Maintaining the +3 valence state of octahedral Fe ions is thus a prerequisite for achieving high resistivity. There are types of additions ...
Electrical conductivity () and dielectric permittivity () together with the pyroelectric coefficient () have been measured for a series of composites containing acrylonitrile butadiene rubber (NBR) and barium titanate ceramic in the form of powder. The possibility of obtaining thermal electrets is ...
Leakage currents (DC conductivity) were also studied as a function of the applied field and temperature. At room temperature the dielectric constant is 18.5 (100 kHz), the dissipation factor is 4 × 10 3 and the conductivity is 6 × 10 16 S/cm (2.7 μm thick films). A dielectric ...
Particularly, PPy is one of the most recognized conductive polymers for its high conductivity and excellent biocompatibility (George et al. 2017, 2005, 2009; Oh et al. 2018). Biodegradable conductive hydrogels are also attractive due to their tunable material characteristics such as degradation in ...
