What determines the conductivity of silicon or germanium when doped with group 13 elements?

Options

  1. AThe number of electron holes
  2. BThe presence of unpaired electrons
  3. CThe movement of free electrons
  4. DThe presence of positrons

Correct answer

C. The movement of free electrons

Step-by-step solution

The conductivity of silicon or germanium when doped with group 13 elements is determined by the movement of free electrons.
