10.) (Based on Neaman, Problem 5.14) - A particular semiconductor material has / = 1000 em-/V . S. Up 600 cm-/V - s and Nc - Nv - 1019 em 3. Assume all of these parameters are independent of temperature. The measured conductivity of the intrinsic material is o - 10 5 (0 . em) at 7 - 300K. Find the conductivity at 500K. Hint: you'll need to find the gap energy first. Answer: 5.80 x 10 3 (0 . em)-1
