8. The Pauli Exclusion Principle states a. Quantum numbers can change for a specific electron b. No two electrons can occupy the same quantum state at the same time in a given system c. All quanturn states in a system must be filled d. As long as electrons are moving,they can have the same quantum number 9. When comparing the Czochralski and Float Zone methods of semiconductor crystal growth a. The Czochralski method was discovered 100 years ago b. The Float Zone method creates crystals with that contain more impurities c. Both methods require little or no heat d. The Czochralski method is only used to make silicon crystals 10. The effective mass of a particle a. Takes into account the internal forces on a particle while moving through a material b. Depends on the material in which the particle exists c. Can never be negative d. Both (a) and (b) Part 2:Calculation Questions (70 points) 1. For the figures below, find the Miller indices for the planes shown (10 pts) a. 1/2 1/3 b. C.

Explanation / Answer

Particles such as Electrons, protons and neutrons are fermions can NOT be in the same location with the same energy state at the same time.

This means that two electrons going around the same nucleus can NOT both be in the exact same state at the same time.

Thus Paulis exclusion principle states that "No two electrons can occupy the same quantum state at the same time in the given system"

Ans is option B
