✦ Synopsis

High quality and large-sized Rb 0.3 MoO 3 single crystals were synthesized by molten salt electrolysis method. X-ray diffraction (XRD) patterns and rocking curves, as well as the white beam Laue diffraction of X-ray images show the crystals grown by this method have high quality. The lattice constants evaluated from XRD patterns are a 0 ¼ 1.87 nm, b 0 ¼ 0.75 nm, c 0 ¼ 1.00 nm, b ¼ 118:83 : The in situ selected area electron diffraction (SAED) patterns along the ½101; ½111 and ½103 zone axes at room temperature indicate that the Rb 0.3 MoO 3 crystal possess perfect C-centered symmetry. Temperature dependence of the resistivity shows this compound undergoes a metal to semiconductor transition at 183 K.
