Liu, C. Lin] Single crystals of Fe1+δ Te1−x Sex (0≤x≤0.5) were grown via both Bridgman and self-flux techniques. Large crystals of size ∅10×50mm could be obtained with the Bridgman method. The excess of iron, δ≥0.07, at interstitial sites was observed to deteriorate the superconductivity of the samples. Study of semiconducting and Curie-Weiss-like behavior indicates that an appearance of a hump for Fe1+δ Te0.60Se0.40 (δ≤0.04) is more pronounced for the self-flux growth than for the Bridgman method. This was observed via measurement of the normal state of resistivity and magnetic susceptibility, which decrease with lower temperature. Furthermore, our results give evidence that the phase with x∼0.40 is readily formed in the self-flux method despite the use of various ratios of initial mixtures.
