Effect of Pressure on Thermoelectric Power of Ni(S_<1-x>Se_x)_2
Electrical resistivity and thermoelectric power measurements were carried out on single crystals of Ni (S<SUB>0. 9</SUB>Se<SUB>0. 1</SUB>) <SUB>2</SUB> under hydrostatic pressure up to 8. 0 GPa for electrical resistivity measurements and up to 1. 5 GPa for thermoelectric power measurements, respectively, in a temperature range between 4. 2 K and 300 K. The relation Se 10%=1. 0 GPa is confirmed to be valid also for the thermoelectric power of Ni (S<SUB>1-x</SUB>Se<SUB>x</SUB>) <SUB>2</SUB> compounds. According to a one-band two-carriers model, the contributions of electron or hole are nearly in balance below approximately 100 K, while the contribution of hole dominates that of electron above approximately 100 K.
