Abstract
The electrical properties of (MxV1–x)2O3 (M = A1, Cr, Fe, Ga, Rh, Ti) have been investigated. Only Al- and Cr-doped V2O3 exhibit electrical transitions close to room temperature. X-ray diffraction shows that no critical lattice parameter can be identified to correlate with the occurrence or absence of this transition. Some features are described which cannot readily be reconciled with existing theories of the metal-insulator transition.
