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 YBa2Cu3O7−δ and n-type infinite-layer Sr0.9Ln0.1CuO2 (Ln = La, Gd) systems with results from p-type Bi2Sr2CaCu2Ox and n-type one-layer Nd1.85Ce0.15CuO4 cuprates, and attribute various non-universal behavior to different competing orders in p-type and n-type cuprates.
