摘要
The electrical behavior of tetracyanoquinodimethane (TCN) mixed transition metal salts (iron, cobalt, nickel and copper) has been investigated in the temperature range 290-33 K at constant pressure of 100 kbar cm-2. The electrical resistivity measurements show a phase transition at nearly 380 and 390 K. The anomaly in the electrical resistivity is discussed. The activation energy of conductance has been calculated below and above the transition temperature. Further information concerning the electrical behavior is obtained by considering the type and mechanism of the conduction processs. This has been achieved by studying the effect of complex formation and temperature on the mobility and the number of charge carriers which take part in the conduction process.
