- In a vacuum chamber filled with argon gas at 100 mTorr, a plasma is ignited resulting to 1% ionization. This is already a "hot plasma" by lab processing standards. Calculate the number density of plasma electrons (should be about the same as the argon ion density due to quasineutrality) in this 1% ionized plasma.1. "Band structure" of "Hatom chain" and "H mole chain" are drawn as "graphs" and "intermediate process". Describe it in detail.Stainless steel typically contains 1% carbon, 1-5% manganese, 0.05% phosphorus, 1-3% silicon, 5-10% nickel, and 15-20% chromium.
