Unformatted text preview: equals the difference between the densities of donors and acceptors. 2. Repeat part (d) of problem 1 for a silicon sample. Is it OK now to assume that the majority carrier concentration approximately equals the difference between the densities of donors and acceptors? What is the percentage of error if one does so? 3. A Si bar is 0.1 cm long and 100 μm 2 in cross-sectional area. Find the current at 300 K with 10 V applied to (a) the Si bar is pure without doping and (b) the Si bar is doped with 1x10 17 /cm 3 phosphorus....
