Abstract
The layer compound ZrSe2 can be grown as a degenerate semiconductor, which is ascribed to the charge transfer effect of the self-intercalated Zr atoms. The self-intercalation is much concerned with the magnitude of the energy gap in the mother crystal. We have ascertained this by the transport measurement of ZrSe2-xSx and TixZr1-xSe2. Intercalation of lithium in ZrSe2 converts the mother crystal into a metallic one. LixZrSe2 (x>0.4) is found to be superconductive below ca. 1.5K.
