A paper Distinguishing the local environments of Ga and Ge in amorphous (Ga2Se3)0.25(GeSe2)0.75 by anomalous X-ray scattering is published in Chalcogenide Letters 15, 1-6 (2018). Local structures of a Ga-Ge-Se glass were investigated by anomalous x-ray scattering at ESRF, which was presented at 8th International Conferece on Amorphous and Nano-Structures Chalcogenides by Benjamin of University of Marburg.

A paper “Lattice distortions in TlInSe2 thermoelectric material studied by x-ray absorption fine structure” is published in Physica Status Solidi A 215(1), 1700416-1-8 (2018). This paper was studied  on a commensurate-incommensurate transition in TlInSe2 thermoelectric material by an XAFS experiment.
