## Homework Statement

A doped silicon ingot is to be grown by the Czochralski technique with a dopant concentration of 10

^{16}boron atoms/cm

^{3}. If k

_{0}= 0.9 for boron/Si, what concentration of boron atoms should be in the melt?

## Homework Equations

C

_{s}/C

_{0}= k

_{0}(1 - m/m

_{0})

^{k0-1}

k0 = C

_{s}/ C

_{l}

## The Attempt at a Solution

I think it's just a case of subbing in the numbers to establish C

_{s}and then using this in the second equation to find C

_{l}, but I'm really confused about what the values of M and M

_{0}should be in this scenario.
