Abstract:Observed frequency dependent optical conductivity σ (ω) of electron-doped cuprate Nd 1.85 Ce 0.15 CuO 4−δ (δ ≈ 0.02, T c ≈ 25 K) superconductors has been theoretically analysed. Starting from an effective two-dimensional (2D) interaction potential for superlattice of electron-doped cuprates treated as a layered electron gas, the spectral function is developed. Calculations of σ (ω) have been made within the two component scheme: one is the coherent Drude carriers responsible for superconductivity and the other… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
