conductivity of silicon
Im just wondering if I did the following question correctly:
Determine the conductivity of silicon at T = 300 K if it is doped with donor impurity atoms at a concentration of 1.25*10^16 cm-3. Assume that the electron and hole mobilities are 1350 cm2 / V-s and 480 cm2 / V-s, respectively.
Because it is a donor I would do the following:
(1.6*10^-19 C)(1.25*10^16 cm^-3)(1350 cm^2/V-s)
(charge electrons)(concentration)(electron mobilities)
Would this be the correct formula to find the conductivity of silicon or would I need to replace 1350 with 480?
Thanks so much!
