The dissection of atomic clusters with local structure in Ga-Sn alloy melts

Abstract

The statistic short-range order (SRO) structure parameters of the Ga-Sn alloy melt are obtained with the X-ray diffractometer. The local atomic and electronic structures around the absorption atoms of Ga and Sn elements are detected by X-ray absorption fine structure spectrum. Centered on the absorption atom, the atom cluster structure was dissected and the atom cluster model was established. Unlike the ordinary liquid metal structure, the local atomic structure demonstrates that the liquid Ga-Sn alloy is not characterized by a dominant icosahedral short-range order. Specially, Sn atoms aggregate in Ga91.6Sn8.4 alloy, giving rise to a phase separation that exhibits compositional disorder.

Liquid metal with solvents for CO2 capture

“…As shown in Table 1, the minimum distances between atoms are larger than the data in the literature obtained by extended X-ray absorption fine structure (EXAFS). 40,41 This strongly proves that the single atom of Ga, In, and Sn exists in GaInSn/PANI/TEMPO. The resistance force of GaInSn/PANI/TEMPO is obtained in Fig.…”

The simulated S(k) values are obtained by using the Fourier transform of g(r) in the ISAACS program.…”
