Electric-field-dependent variable-range hopping conductance in quasi-two-dimensional systems: Application to PrBa2Cu3O7-y-based superconductor–normal-metal–superconductor junctions
Singh, M.; Thompson, Russell B.; Dumas, O. (American Physical Society, 1996-03)We have calculated the hopping conductivity of quasi-two-dimensional systems by using the variable-range hopping conduction mechanism in the presence of an electric field. We considered that the localized states are randomly ... -
Electric-field-dependent variable-range hopping conduction in PrBa2Cu307-y
Thompson, Russell B.; Singh, M. (Taylor & Francis, 1997-02)The variable-range hopping conductivities of quasi-two-dimensional systems in electric fields were calculated for the cases of both constant and energy-dependent densities of states. The localized states were considered ... -
Magnetoconductance due to variable-range hopping in quasi-two-dimensional systems: Application to PrBa2Cu3O7-delta
Thompson, Russell B.; Singh, M. (American Physical Society, 1998-01)In this paper, we have developed a theory of magnetoconductance (magnetoresistance) due to variable-range hopping for quasi-two-dimensional systems. We have included the effect of electric fields on the calculation of the ... -
Small-polaron variable-range hopping in quasi-two-dimensional materials: application to PrBa2Cu3-xGax07-y
Thompson, Russell B.; Singh, M. (Taylor & Francis, 1999-01)We have developed a theory for variable-rangehopping (VRH) due to small polarons in quasi-two-dimensionalsystems at high temperatures.We included the effects of temperature, electric fields, magnetic fields and scattering ...
