Consider a piece of silicon, which you know has a gap of 1.1 eV. At 300 K, you measure a resistance of 2 Ohms. (Hint: You will need to use an accurate value of k (1.380649 × 10-23) and eV-to J conversion (1.602176634 × 10-19) to get the right answer)

1) What is the resistance of this piece of silicon at 77 K?
