对黄铁矿和毒砂电学性质的研究（Golosov，1939；Smith，1947；Fischer 和 Hiller，1956；Gorbatov，1957、1960；Voytkevich 等，1966；Knyazev，1965、1966；Rozova，1969；Suzuki，1970）表明在这些矿物的范围内，可以区分表现出不同类型导电性的品种，即 p-、pn 和 n-黄铁矿和毒砂。某些作者（Knyazev、Berman 等人；Krasnikov 等人；Rozova）讨论了这些品种的类型，描述了矿床的特定成矿类型和矿物形成阶段。化合物和元素中半导体特性的出现是由固体结构中原子键的类型决定的。电子空穴中心负责半导体性质的变化，特别是矿物的热电性质，位于同晶杂质中（Marfunin 和 Bershov，1969）或主要成分的空位中（Kroger，1969）。显然，电性能的变化与矿物的化学成分和晶胞尺寸的变化直接相关。
Research on the electrical properties of pyrite and arsenopyrite (Golosov, 1939; Smith, 1947; Fischer and Hiller, 1956; Gorbatov, 1957, 1960; Voytkevich et al., 1966; Knyazev, 1965, 1966; Rozova, 1969; Suzuki, 1970) has shown that varieties exhibiting different types of conductivity may be distinguished within the limits of these minerals, namely p-, pn, and n-pyrites and arsenopyrites. Certain authors (Knyazev, Berman et al.; Krasnikov et al.; Rozova) discuss the typomorphism of these varieties, characterizing specific mineralgenetic types of deposits and stages of miner al formation.The appearance of semiconductive proper ties in compounds and elements is determined by the type of atomic bond in the structure of the solid. The electron-hole centers, respon sible for the variability of the semiconductive properties and in particular the thermoelectric properties of minerals, are localized in isomorphous impurities (Marfunin and Bershov, 1969) or in vacancies in the principal compo nents (Kroger, 1969). It is clear that the change in the electrical properties is directly related to the variability of the chemical com position and the dimensions of the unit cell of the mineral.
