Question

8. Gold and copper are both metallic conductors that have resistivity in the range of 2x 10-8 am
The semiconductor silicon has a resistivity of 6.4 x 102 om. On an atomic level, what causes the
resistivity of silicon to be so much higher? (3 points)

Answer 1

Answer:

I'm just guessing/deducting here, but:

1. Because the electronegativity of silicon is much stronger causing electrons to be much less conducive.

2. Extra free electrons = is more charged particals that can move freely and thus conduct electricity. So the resistivity will be lowered.
