Abstract:
Doping is the most versatile tool to influence transport properties of a given solid. Simple rules for its application in ionic and covalent materials are formulated. The usual doping concept that relies on hetero-valence effects is extended to homo-valent situations, which exhibit elastic interactions. Another extension refers to incorporation of higher-dimensional dopants such as interfaces or dislocations. The description is kept on a qualitative level for the reader who is mostly interested in materials synthesis and design.
