2) Si and C are both elements in Group IV ogf the periodic table. What property makes one a semiconductor and the other an insulator?

3) I you need a material that can absorb a lot of light in a thin layer would you chose a direct bandgap or indirect bandgap material?

5) What fundamental law requires that electrons and holes be generated thermally in equal numbers?

6) If a Group VI element replaced a Si atom in a Si lattice, how many free electrons would you expect it to contribute?

7) If you were given a p-type material and wanted to move the Fermi level closer to the valence band, would you add donor or acceptor impurities?
