摘要：

The detailed structural properties of La-doped Bi2Sr2-xLaxCuO6 (La-Bi2201, 0 <= x <= 1.1) have been studied by transmission electron microscopy (TEM). The well-known incommensurate supermodulation q(1) in the Bi-based cuprates evolves from a monoclinic superstructure in the pristine Bi2201 phase to an orthogonal one in the La-Bi2201 (x = 0.73) phase. The b-component of the modulation vector (q(1)) for the x = 0.25 sample is about 0.24b* and increases slightly to 0.246b* in the x = 0.84 sample, while it increases significantly to 0.286b* for the x = 1.10 sample. We have revealed a new anti-phase stripe superstructure in all the La-doped Bi2201 samples, giving rise to a new modulation with a vector q(2). This q(2) modulation is directly evolved from the orthogonal modulation q(1) through an addition of the anti-phase structure so that its vector q(2) is equal to q(1b)/2. We also discussed the implication of these structural studies on the electronic structure by angle-resolved photoemission spectroscopy (ARPES) experiments in La-Bi2201.
