Abstract:
Electrochemical copper intercalation in ZrTe3 yields the new metallic
ternary phase CuxZrTe3 with a maximum stoichiometry of x=1.9. The charge
is balanced by filling the sigma* antibonding Te p bands, as monitored
by XANES spectroscopy. The reaction is accompanied by an increase in the
a lattice dimension of 9%. This observation is explained by theoretical
calculations. (C) 1997 Elsevier Science S.A.
