Journal ArticleDOI
Superconductivity produced by electron doping in CuO 2 -layered compounds
TL;DR: It is discovered that the Ce4+doping and subsequent annealing in reducing atmosphere give rise to 24-K superconductivity in the Nd2CuO4-type structure with sheets of Cu-O squares, in contrast to the previously reported high-Tccuprates.
Journal ArticleDOI
Discovery of microscopic electronic inhomogeneity in the high-Tc superconductor Bi2Sr2CaCu2O8+x
S. H. Pan,J. P. O'Neal,Robert L. Badzey,C. Chamon,Hong Ding,Jan R. Engelbrecht,Ziqiang Wang,Hiroshi Eisaki,S. Uchida,Anjan K. Gupta,K.-W. Ng,Eric Hudson,Kristine Lang,J. C. Davis +13 more
TL;DR: In this paper, an electronic inhomogeneity was observed in high-Tc superconductor Bi2Sr2CaCu2O8+x using scanning tunnelling microscopy/spectroscopy.
Journal ArticleDOI
Imaging the granular structure of high-Tc superconductivity in underdoped Bi2Sr2CaCu2O8+x
Kristine Lang,Vidya Madhavan,Jennifer Hoffman,Eric Hudson,Hiroshi Eisaki,S. Uchida,J. C. Davis +6 more
TL;DR: In this article, the spatial interrelationships between STM tunneling spectra in underdoped Bi2Sr2CaCu2O8+x were investigated and it was shown that the electronic structure can be divided into 3nm diameter domains with superconducting characteristics and local energy gap delta 50(2.5) meV.
Journal ArticleDOI
Imaging the granular structure of high-Tc superconductivity in underdoped Bi2Sr2CaCu2O8+δ
Kristine Lang,Vidya Madhavan,Jennifer Hoffman,Eric Hudson,Eric Hudson,Eric Hudson,Hiroshi Eisaki,Hiroshi Eisaki,S. Uchida,J. C. Davis,J. C. Davis +10 more
TL;DR: In this article, underdoped Bi2Sr2CaCu2O8+δ superconductors are shown to be a mixture of two different short-range electronic orders with the long-range characteristics of a granular superconductor.
Journal ArticleDOI
Superconductor-to-nonsuperconductor transition in ( La 1 − x Sr x ) 2 CuO 4 as investigated by transport and magnetic measurements
TL;DR: Remarkable changes associated with the superconductor-to-nonsuperconductor transition are observed both in the Hall coefficient and the magnetic susceptibility, suggesting the modification of both charge and spin states.
