Experimental investigation of the asymmetric spectroscopic characteristics of electron- and hole-doped cuprates

Abstract

Quasiparticle tunneling spectroscopic studies of electron- (n-type) and hole-doped (p-type) cuprates reveal that the pairing symmetry, pseudogap phenomenon and spatial homogeneity of the superconducting order parameter are all non-universal. We compare our studies of p-type YBa_2Cu_3O_{7-x} and n-type infinite-layer Sr_{0.9}Ln_{0.1}CuO_2 (Ln = La, Gd) systems with results from p-type Bi_2Sr_2CaCu_2O_x and n-type one-layer Nd_{1.85}Ce_{0.15}CuO_4 cuprates, and attribute various non-universal behavior to different competing orders in p-type and n-type cuprates.
