Abstract

Using newly developed X-ray low temperature camera, 4k_F periodic modulation was observed in organic quasi one-dimensional (Q1D) compounds (DMe-DCNQI)₂Ag(abbreviated as DMe) and (DI-DCNQI)₂Ag (abbreviated as DI). From 4k_F satellite reflection intensity distribution in q-space, periodic molecular displacement in DMe and periodic molecular deformation possibly related with molecular valence ordering in DI were found. These modulation patterns suggest occurrence of 4k_F bond CDW in DM and 4k_F site CDW in DI. The 4k_F site CDW possibly caused by a marked intersite correlation V, can be interpreted as a Wigner crystal.
