Abstract
Modification and doping are both terms which used to display improvement of sensory characteristics of materials, particularly their selectivity. But these processes are different in the way how they influence on material’s properties. This review concentrates on differences between modification and doping and their impact on parameters of sensitive materials for semiconductor gas sensors, in particular on characteristics of SnO2 as one of the most promising sensor material.
