WitrynaThis allows us to treat the original semiconductor as unaffected in its electronic properties, with the impurity atoms only increasing the electron concentration. A limit to donor concentration in order to allow treatment as shallow donors is approximately 10 19 cm −3. Energy levels due to impurities deeper in the bandgap are called deep levels. Witryna22 lut 2024 · impurity level An energy level outside the normal band of the material, caused by the presence of impurity atoms. Such levels are capable of making an insulator semiconducting. The impurity atom may be a donor or acceptor. If a donor, the impurity induces electronic conduction through the transfer of an electron to the …
