AbstractThe electronic properties of a strongly correlated heterostructure consisting of t-J layer and metallic layer have been investigated by using the Gutzwiller projected mean-field approximation. Considering the proximity effect due to the large pseudogap energy scale of t-J layer, a large superconducting gap could be induced on the metallic layer. This enhanced superconducting gap may be even larger than that of the t-J layer. Related physical quantities including spectral functions and density of states are obtained. The consequences of these results on experiments are discussed. © 2010 The American Physical Society.
