A silicon sample A is doped with 1018 atom/cm3 of Boron and another silicon sample B of identical dimensions is doped with 1018 atom/cm3 of Phosphorous. If the ratio of electron to hole mobility is 3, then the ratio of conductivity of sample A to that B is:
1
\(\frac{3}{2}\)
2
\(\frac{2}{3}\)
3
\(\frac{1}{3}\)
4
\(\frac{1}{2}\)
