Rare-earth vanadites LnVO/sub 3/ (Ln = La-Lu and Y) were prepared. These compounds have a perovskite-type structure with space group Pbnm. Electrical conductivity of each LnVO/sub 3/ has been studied in vacuum below room temperature. Results show that all rare-earth vanadites are extrinsic, p-type semiconductors having an activation energy of about 0.1 eV. Resistivity increases along the lanthanide series from LaVO/sub 3/ to GdVO/sub 3/ with quasi-constant values observed between TbVO/sub 3/ and LuVO/sub 3/. These results are discussed in terms of Goodenough's localized electron model.
