Electronic Structure and Electron Correlation in LaFeAsO_{1-x}F_x and LaFePO_{1-x}F_x

Walid Malaeb, Teppei Yoshida, Takashi Kataoka +10

Photoemission spectroscopy is used to investigate the electronic structure of the newly discovered iron-based superconductors LaFeAsO_{1-x}F_x and LaFePO_{1-x}F_x. Line shapes of t…

Proximity-Induced Nodal Metal in an Extremely Underdoped CuO Plane in Triple-Layer Cuprates

Shin-ichiro Ideta, Shintaro Adachi, Takashi Noji +15

ARPES studies have established that the high- cuprates with single and double CuO layers evolve from the Mott insulator to the pseudogap state with a Fermi arc, on which t…
