1. Consider an intrinsic material at 300 K. Under pressure, the band gap is reduced from 1.6 to 1.5 eV. By what factor does the electrical conductivity of this material increase?

2. Suppose you wish an intrinsic material to remain an electrical insulator at 800 K, having less than one conduction electron per cubic centimeter of material. What is the minimum band gap that is needed?
