摘要：

We have used electrical resistivity and X-ray diffraction measurements to study SmTe2-x (x similar to 0.1). The crystal structure is highly two-dimensional, but no evidence was found at room temperature for either charge density wave or ordered defect structures. Unlike the previously studied Sm polytellurides, the electrical resistivity of SmTe1.9 is insulating, but displays a similar large electronic anisotropy.
