Witryna1 maj 2024 · In this work, a hexagonal quantum dot (HQD) with hydrogenic donor impurity was considered. We have first employed the finite element method (FEM) to determine energy eigenvalues and eigenstates of the system. Then, we have calculated the binding energy, absorption coefficients (ACs), refractive index changes (RICs), … WitrynaImpurity control is an essential aspect of quality control in individual monographs of the Ph. Eur. In this module, you learn about the Ph. Eur. policy on impurity control. It covers all types of impurities, whether they are organic, inorganic (including elemental impurities), solvents or DNA-reactive impurities such as N-nitrosamines.
