Doped silicon and germanium are technologically the most important types of semiconducting material . 添加硅和锗在工艺上是半导体物质中最重要的类型。
2.
Standard methods for measuring conductivity type of extrinsic semiconducting materials 非本征半导体材料导电类型测试方法
3.
Controlled concentrations of specific donors or acceptors may be intentionally added into materials to form extrinsic semiconductor using various techniques . such an alloying process in semiconducting materials is termed doping 控制特定施主和受主原子的浓度，进而运用各种方法能动地填加，这种在半导体材料中加入合金成分的过程称为掺杂。
