Abstract
The differential conductance, (dI/dV), on YBa2Cu3Oy/PrBa2Cu3O y/YBa2Cu3Oy (YBCO/PBCO/YBCO) sandwiched junctions and YBa2Cu3Oy/Y0.5Pr 0.5Ba2Cu3Oy (YBCO/YPBCO) superlattices was measured with STM at various temperature ranges to investigate the proximity effects. The dI/dV curves show conductance peaks at low temperatures and the energy gap, 2Δab, derived from the peaks is equal to about 46 meV for YBCO/PBCO/YBCO sandwiched junctions, which is consistent with the data obtained from reported data on YBCO single crystals whereas the YBCO/YPBCO ((120 Å/60 Å)x8) superlattices, due to the reduction of Tc, show smaller gap value.
