A - ?
B - ?
C - ?

Answer 1

There is a Net Increase in Conductivity
A - Freeze-Out Region
B- Extrinsic Region
C - Intrinsic Region

Question 2

What happens the Freeze-Out Region?

Hint: Donor ____, ____ to ____ until ____ is ________ to overcome _______ ___ ______

Answer 2

Donor electrons struggle to cross until Heat is sufficient to overcome scattering from substitution

Question 3

What happens in the Extrinsic Region?

Answer 3

Very few electrons cross

Question 4

What happens in the Intrinsic Region?

Answer 4

More Intrinsic electrons = Higher concentration, more phonons, and lower mobility
