| dc.description | Rb-substitution effect on the metal-insulator transition of hollandite vanadate, K<sub>2</sub>V<sub>8</sub>O<sub>16</sub> has been investigated. The metal-insulator transition is accompanied by a charge ordering and a structural change from a tetragonal to a monoclinic structure with an increase of volume in the low-temperature monoclinic insulator phase. Rb-substitution for K atoms continuously raises the transition temperature up to 240 K for Rb<sub>2</sub>V<sub>8</sub>O<sub>16</sub> from 160 K for K<sub>2</sub>V<sub>8</sub>O<sub>16</sub> and does not make the transition broad in contrast to Ti-substitution. This significant rise of transition temperature can be understood as a negative chemical pressure effect caused by Rb-substitution. |
