It was shown that substitution of Ni atoms (3<em>d</em><sup>8</sup>4<em>s</em><sup>2</sup>) by Rh atoms (4<em>d</em><sup>8</sup>5<em>s</em><sup>1</sup>) in the structure of ZrNiSn compound generated the structural defects with acceptor nature, and holes became the main charge carriers in the ZrNi<sub>1-</sub><em><sub>x</sub></em>Rh<em><sub>x</sub></em>Sn at low temperature. Based on analysis of the motion rate of the Fermi level Δ<em>ε</em><sub>F</sub>/Δ<em>х</em>&nbsp;in ZrNi<sub>1-</sub><em><sub>x</sub></em>Rh<em><sub>x</sub></em>Sn to the valence band and change of sign of thermopower coefficient from positive to negative it was suggested that the structural defects of acceptor and donor natures were generated simultaneously (donor-acceptor pairs), and deep donor band&nbsp;<em>ɛ</em><sub>D</sub><sup>2</sup>&nbsp;was formed.</p> ER -
