Above 167 K Ni(C3S5)2 exhibits a semiconductive behaviour, below this temperature it turns to exhibit metallic conductivity. Based on a tight-binding energy band calculation, an expression for the number of conducting electrons has been deduced.

文摘The molecular based electrical conductor Ni(C3S5)2 has been prepared and its conductivity has been measured from room temperature down to 60 K. Above 167 K Ni(C3S5)2 exhibits a semiconductive behaviour, below this temperature it turns to exhibit metallic conductivity. Based on a tight-binding energy band calculation, an expression for the number of conducting electrons has been deduced.
