A. Schattke et al., INVESTIGATIONS ON THE C-AXIS TRANSPORT-PROPERTIES OF YBA2CU3O7-DELTA PRBA2CU3O7-DELTA THIN-FILM SUPERLATTICES/, IEEE transactions on applied superconductivity, 7(2), 1997, pp. 2727-2729
In this paper we report on the c-axis transport properties of YBa2Cu3O
7-delta/PrBa2Cu3O7-delta superlattices. We describe the preparation, c
haracterisation and patterning of thin film superlattices into suitabl
e mesa structures via standard photolithography. Resistive measurement
s were carried out which point towards an inhomogenius current distrib
ution in the normal state resistance. Below T-c, the c-axis properties
determine the temperature dependent resistance. Resonant tunneling is
observed with no Josephson current.
