ABSTRACT

The dependence of the resistance of the transition contact rk and the adhesion work of extruded samples of the Bi0.85Sb0.15 solid solution on the magnetic field strength and temperature was investigated. It was found that the resistance of the transition contacts of the Bi0.85Sb0.15 - contact alloy structures is determined mainly by the resistance of the n- Bi0.85Sb0.15 solid solution - Bi0.85Sb0.15 solid solution structure heavily doped with acceptor impurity atoms
Sn and Pb diffusing from the contact alloy into the near-contact region of the crystal.
