dc-conduction mechanism in Fe-doped polystyrene films

Electrical Conduction and mechanical properties of irradiated clay nanoparticles /SBR rubber composites

“…We recognize that at low voltages, the current increased gradually with applied voltage and at higher voltages; the rate is slower. This behavior can be explained in terms of Schottky's field-assisted thermoionic emission charge transport (Pillai, Narula et al (1981), Sharma, Adinarayana et al 1991, Tyagulskii, Tyagulskii et al 2013, and the relation for current will be:-Where A, is the Richardson constant, s, the electrode area, ɸ, the metal work function , d, the thickness of the dielectric Ɛ , K, the permittivity ,K, the Boltzmann constant, and T, is the temperature in Kelvin. If V expressed in volts and d in cm, the value of C is 4.058 For the Poole-Frenkel effects, the value of C, replaced by 2C.…”
