A) \[5.634e\,{{\Omega }^{-1}}{{m}^{-1}}\]
B) \[1.968\,{{\Omega }^{-1}}{{m}^{-1}}\]
C) \[3.421\,{{\Omega }^{-1}}{{m}^{-1}}\]
D) \[8.964\,\,{{\Omega }^{-1}}{{m}^{-1}}\]
Correct Answer: B
Solution :
As conductivity of semiconductor, \[\sigma =e({{n}_{e}}{{\mu }_{e}}+{{n}_{r}}{{\mu }_{n}})\] \[=1.6\times {{10}^{-19}}(5\times {{10}^{18}}\times 23+{{810}^{19}}\times 0.01)\] \[=1.968\,{{\Omega }^{-1}}{{m}^{-1}}\]You need to login to perform this action.
