1. Compute the thermal equilibrium constant K of the electron-hole pair generation-recombination reaction in silicon at 300K, 600K and 900K.
2. A test charge Is generated Inside a pure Si at T=300K. How long does it take for the test charge to decay to 10% of its original magnitude?
Where does the test charge go and give the reasons? Describe carefully what is meant by a test charge - its volume, the number of electrons it contains, etc.
