Question

How could you make compensated silicon that has twice as many acceptors as donors?

Short answer

To make compensated silicon have acceptors twice as many as donors, we need to add twice the number of n-type impurities as the number of p-type impurities.

Step-by-step solution

Step 1:

Compensated semiconductors are dopped with both n-type and p-type impurities. To make a compensated silicon have acceptors twice as many as donors, we need to add twice the number of n-type impurities as the number of p-type impurities.

Step 2:

Hence to make compensated silicon have acceptors twice as many as donors, we need to add twice the number of n-type impurities as the number of p-type impurities.
