Abstract
The solid solutions V1−xTixO2 (0.02<−x<−0.4) which are monoclinic at room temperature (with the monoclinicity decreasing with increasing x) transform to rutile structures at Tt. The Tt, H as well as the conductivity jump (at Tt) decrease with increase in x. Incorporation of 2 at.% of Nb (or Mo) lowers the Tt of VO2 considerably, while 10% Nb stabilizes the high-temperature rutile structure. The high temperature rutile phases of all the solid solutions show semiconducting behavior indicating that the conductivity anomalies correspond to semiconductor-semiconductor transitions.
