Lightly doping concentration 10 16-10 18
WebThus, in this way, also, we find that the measured doping densities are much lower than needed to exceed the np value, deduced from the experimental data, while 10 16 cm −3 … WebDoping concentration is the quantity of impurities added to semiconductors to change their properties. Generally, doping concentrations are measured in terms of the ratio of p to n. In this way, semiconductors can be classified as i-type or n-type. Doping concentrations of i-type materials are more abundant than those of n-type materials.
