Non Uniform Doping Of Semiconductor
1. Which of the following will be true for a semiconductor where two neighboring regions have different doping concentrations of n-type dopant?
2. What does the built-in potential between two adjacent locations depend on?
3. What will be built in potential value at 25 C between two locations with doping 5x1012 and 2*1015?
4. A 1D semiconductor of length l is uniformly doped with n-type dopants for 0 ≤ x ≤ l/2 and undoped for l/2 ≤ x ≤ l. What is the electric field E(x) in the undoped region (l/2 ≤ x ≤ l)?
