The Relationship between Natural Pyrite and Impurity Element Semiconductor Properties: A Case Study of Vein Pyrite from the Zaozigou Gold Deposit in China

Pyrite is a common sulfide mineral in gold deposits, and its unique thermoelectricity has received extensive attention the field of exploration. However, there still lack detailed research direct evidence about how impurity elements affect semiconductor properties. In this paper, combined with first-principles calculations, laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) mapping technology situ Seebeck coefficient scanning probe were used to study law changing properties pyrite containing such as As, Co, Ni, Cu. The results showed that arsenic P-type semiconductor, pyrites Cu, other are N-type semiconductors. When As supplemented elements, type changed N-type. Co addition did not change arsenic-rich pyrite. formed under different temperature conditions tended be enriched combinations leading relative accumulation or pyrites.
