Witryna22 maj 2024 · Electron Energy Distribution. The Fermi energy level of a semiconductor, denoted \(E_f\), represents the energy level at which the probability of finding an electron is one half [9] [10, p. 432,543]. The Fermi level depends on temperature, and it depends on the impurities in the semiconductor. Chemists sometime call the Fermi level by … WitrynaImpurities can be classified into the following categories: • Organic impurities (process- and drug-related) • Inorganic impurities • Residual solvents Organic impurities can arise during the manufacturing process and/or storage of the new drug substance. They can be identified or unidentified, volatile or non-volatile, and include:
