Long and Short Range Ordering of CuInSe 2

Abstract

Cu K-edge X-ray Absorption Fine Structure (XAFS) measurements were performed on CuInSe 2 samples with different compositions near the A I B III C 2 VI stoichiometry and CuIn 5 Se 8 . The Cu-Se bond length was determined to be independent of the Cu content. This result is consistent with first-principle total energy calculations for this system.
