2.3 Mineral Groups. Most minerals are made up of a cation (a positively charged ion) or several cations and an anion (a negatively charged ion (e.g., S 2– )) or an anion complex (e.g., SO 42–). For example, in the mineral hematite (Fe 2 O 3 ), the cation is Fe 3+ (iron) and the anion is O 2– (oxygen). We group minerals into classes on the ...The total DOS of perfect galena and galena containing Ag, Cu, Bi, and Mn impurities is shown in Fig. 7.21. It can be seen that the total DOS of n-type surfaces (Bi-doped and Mn-doped surface) shifts to negative energy, compared with the p-type surface (Ag-doped, Cu-doped, and perfect surface), indicating that the electronic energy level of the ...PERCENT TO FORMULA !
