Unformatted text preview: CsH BaS b) CsCl and AgZn crystallize in the same unit cell type. For CsCl, a = 4.20 A; for AgZn, a = 3.16 A. AgZn CsCl c) Sr crystallizes in the FCC arrangement, while Rb crystallizes in the BCC arrangement. They have about the same value of a. Sr Rb 3. Identify the four labeled positions in the following diagram: (Hint: you may wish to read Section 8.6 in the textbook to help you answer this question and the next question.) 1 is the conduction band 2 is the band gap 3 is the fermi level 4 is the valence band Section 8.6 4. Materials A, B, and C have the following band structures. One is a conductor, on a semiconductor, and an insulator. Identify each. A: insulator B: conductor C: semiconductor...
