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. WitrynaTranscribed Image Text: Boron atoms are added to a Si film resulting in an impurity density of 4 x 10¹6 cm-³. (a) What is the conductivity type (N-type or P-type) of this film? (b) What are the equilibrium electron and hole densities at 300 K and 600 K? (c) Why does the mobile carrier concentration increase at high temperatures?
WitrynaThe effects of various metallic impurities, both singly and in combinations, on the performance of silicon solar cells have been studied. Czochralski crystals were grown with controlled additions of secondary impurities. The primary dopants were boron and phosphorus while the secondaires were: A1, B, C, Ca, Co, Cr, Cu, Fe, Mg, Mn, Mo, …
