We studied the electrical resistivity and thermoelectric power of pyrite in the temperature range, 78-300 K. Electrical resistivity measurements show diverse transitions at different temperatures especially a semiconducting pumping transition, where semiconducti-vity sets in at 115 K. The insulator to metal transition in pyrite is referred to as shallowing of deep quantum wells. The shallowing of quantum well sets in at 158 K. At 195 K, the pyrite behaves as a pure metal. Further a comparative study of experimental thermoelectric power with theoretically estimated result is made.
