Question: Derive the following expression for the average impurity concentration over a particular length of crystal layer, z 2 z 1 , after one pass

Derive the following expression for the average impurity concentration over a particular length of crystal layer, z₂ – z₁, after one pass or partial pass of zone melting.

e(1 - K) K(z2 – Z1) -lеxp( - 22 K /е) — ехp( -21 К /0)] + 1 W avg = Wo

Using the results of Example 17.14, calculate wavg for z1 = 0 and z2/ℓ = 9.

e(1 - K) K(z2 Z1) -lxp( - 22 K /) p( -21 /0)] + 1 W avg = Wo
