The Fermi surface and band folding in La2-xSrxCuO4, probed by angle-resolved photoemission
2010 (English)In: New Journal of Physics, ISSN 1367-2630, Vol. 12, 125003- p.Article in journal (Refereed) Published
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 unusual doping dependence. The appearance of the folded band suggests that a Fermi surface reconstruction is doping dependent and could already occur at zero magnetic field.
