Abstract
The crystal structure of a Cu-richβ-phase in the system Cu-In-Se with the composition Cu14.0In16.7Se32 quenched from 750° C, has been determined with single crystals. The investigated single crystal of this Cu-richβ-phase has the composition Cu14In16.7Se32 and crystallizes witha = 1.1534(4) nm in the space groupP−43m. The cations are statistically distributed together with vacancies, but show strong preferences for distinct positions. The number of vacancies is estimated from the crystal structure analyses and is found to be much less than in the Cu-poorβ-phase. The crystal structure is compared with that of an ordered Cu-richβ-phase.
