A sample of silicon contains 10 to the power of 18 donors m3 and 10 to the power of 16 acceptors m3. The donor ionisation energy is 50 meV. Calculate the temperatures at which the electron concentrations are
(a) 10 times the saturated value
(b) 0.1 the saturated the saturated value.
calculate the intrinsic electron concentration, and assume for part (a) that the energy gap at the required temperature is 1.1 eV. An iterative method will be required for both parts.
Could someone please help. I don't know what the saturated value in the 1st place is and don't know what equation to use. A solution or help in the right direction would be useful.
