The coexisting of insulating and metallic/superconducting phases and their competing effects in various underdoped cuprates

摘要: We show that the unconventional electron–phonon interactions and polaronic effects, charge inhomogeneity ordering in underdoped cuprates result nanoscale phase separation occurrence of competing coexisting insulating metallic/superconducting phases. identify possible types localized mobile carriers these systems, which segregate into (carrier-poor) (carrier-rich) regions as a their specific ordering. found coexistence two metallic phases can persist lightly doped on local scale, while three insulating, superconducting is expected global scale. demonstrated effects are manifested unusual temperature dependences magnetic susceptibility resistivity su...
