WebCharacterisation of the Fermi surface and phase transitions of (BEDO-TTF)2 ReO4·(H2O) by physical property measurements and electronic band structure calculations: Erscheinungsdatum: 1994: Dokumentart: Zeitschriftenartikel: Erschienen in: Zeitschrift für Physik, B 94 (1994), S. 39-47. WebWe have performed an angle-resolved photoemission spectroscopy (ARPES) study of the undoped and electron-doped iron pnictides BaFe 2−x Co x As 2 (Ba122) (x=0,0.14) and studied the Fermi surfaces (FSs) and band dispersions near the Fermi level. The FS sheets we observed are consistent with the shrinkage of the hole-like pockets around the …
