Role of Holes in Determining Resistivity and Hall Effect in Crystals of YB2Cu3O7-δ and Bi2Sr2CaCu2O8 δ ()
ABSTRACT
Electrical transport properties of superconducting materials are a widely studied area in superconductivity. In this study, the role of holes in determination of resistivity, Hall coefficient and Hall angle has been explored using a two-band model due to co-existence of holes and electrons in high-Tc YB2Cu3O7-δ and Bi2Sr2CaCu2O8-δ. The results obtained from this study show that hole resistivity decreases with increase in the ratio while the Hall coefficient is non-linearly dependent on the hole resistivity. An increase in the hole scattering rate causes a drop in the Hall scattering angle.
