Description
Temperature dependences of the specific electroresistance, Seeback coefficient, and structural characteristics of a heavily Co doped n-TiNiSn intermetallic semiconductor, TiNi-1-xCoxSn, have been studied in the temperature range T=80/380 K. The corresponding electron density of states has been calculated. Co atoms at concentrations x< 0.03, were found to occupy the crystallographic positions of Ti and Ni ones with different occupation numbers and act as defects of the donor or acceptor nature, respectively
