The Fermi surface and band folding in La2-xSrxCuO4, probed by angle-resolved photoemission

Joël Mesot, Elia Razzoli, Martin Mansson, Johan Juul Chang

A systematic angle-resolved photoemission study of the electronic structure of La2-xSrxCuO4 in a wide doping range is presented in this paper. In addition to the main energy band, we observed a weaker additional band, the (pi, pi) folded band, which shows ...

Electronic structure of La1.48Nd0.4Sr0.12CuO4 probed by high- and low-energy angle-resolved photoelectron spectroscopy

Joël Mesot, Martin Mansson, Johan Juul Chang

We present angle-resolved photoelectron spectroscopy data probing the electronic structure of the Nd-substituted high-T-c cuprate La1.48Nd0.4Sr0.12CuO4. Data have been acquired at low and high photon energies, h nu=55 and 500 eV, respectively. The two extr ...

Spectroscopic evidence for preformed Cooper pairs in the pseudogap phase of cuprates

Joël Mesot, Elia Razzoli, Martin Mansson, Johan Juul Chang

Angle-resolved photoemission on underdoped La1.895Sr0.105CuO4 reveals that in the pseudogap phase, the dispersion has two branches located above and below the Fermi level with a minimum at the Fermi momentum. This is characteristic of the Bogoliubov disper ...

Electronic structure near the 1/8-anomaly in La-based cuprates

Joël Mesot, Martin Mansson, Johan Juul Chang

We report an angle-resolved photoemission study of the electronic structure of the pseudogap state in La1.48Nd0.4Sr0.12CuO4 (T-c < 7 K). Two opposite dispersing Fermi arcs are the main result of this study. Several scenarios that can explain this observati ...
