TRANSPORT PHENOMENA IN THE MAGNETICALLY MODULATED SPINELS : Zn1-xCuxCr2Se4 (WHERE 0.0 ≤x≤ 1.0)

T. Gro , H. Duda , J. Warczewski

The spinels under study are p-type semiconductors showing a change of the conductivity character from the conductive into metallic one at x ~ 0.3. An increase of the electrical conductivity with the copper concentration in a sample is linked both with the increase of the hole mobility and the hole concentration. For x ≥ 0.05 partial degeneracy of the semiconductor state is observed.
