Transport properties of VSe 2 intercalated with hydrazine

The temperature dependence of the resistivity of the intercalation complex VSe2(N2H4)0.6 has been measured between 4.2K and 450K. The resistive anomaly associated with charge density wave formation observed at 110K in pure VSe2 is found at a higher temperature, of 165K, in the intercalated system. The authors discuss this behaviour in terms of the increased vanadium d-band occupation which results from charge transfer from the hydrazine.
