Unformatted text preview: two samples of material. One is pure metallic zinc (Zn), and the other is pure silicon (Si). The electrical resistivity of pure polycrystalline zinc at 20 oC is 5.9 μΩ ­m, and the electrical resistivity of pure singlecrystal silicon at 20 oC is 6400 Ω ­m. A. Sketch possible energy ­band diagrams characteristic of pure Zn and pure Si. B. Suppose each sample is heated to 200 oC. How would you expect the resistivity of each material to change, if at all. Briefly explain your reasoning. C. Suppose that each material is alloyed/doped by a small amount of...
