In this paper we report on the c-axis transport properties of YBa 2Cu3O7-?/PrBa2Cu3 O7-? superlattices. We describe the preparation, characterisation and patterning of thin film superlattices into suitable mesa structures via standard photolithography. Resistive measurements were carried out which point towards an inhomogenous current distribution in the normal state resistance. Below Tc, the c-axis properties determine the temperature dependent resistance. Resonant tunneling is observed with...In this paper we report on the c-axis transport properties of YBa 2Cu3O7-?/PrBa2Cu3 O7-? superlattices.
