Question

A Si sample has been doped with 10^17 Arsenic atoms per cm^3. The sample is then further doped with 9*10^16 Boron atoms per cm^3 Using the answers provided in the previous questions, now calculate the conductivity of the sample at 27 °C (room temperature). Hint: at room temperature all the dopants will be ionized (also after the further doping of Boron atoms) Choose the appropriate value of the mobility among ?n = 1500 or = 800 or = 500 [cm^2 V^-1 s^-1] ?p = 400 or = 300 or = 200 [cm^2 V^-1 s^-1] 0.8 [? cm ] 3.08 [?^-1 cm^-1] 0.8 [?^-1 cm^-1] 3.08 [? cm ]

Step 1

- The sample is initially doped with \(10^{17}\) Arsenic atoms per cm\(^3\) (donors, \(N_D\)). - The sample is further doped with \(9 \times 10^{16}\) Boron atoms per cm\(^3\) (acceptors, \(N_A\)). Since Arsenic (donor) and Boron (acceptor) are both present, the Show more…
