Q
What happens the Freeze-Out Region?
Hint: Donor ____, ____ to ____ until ____ is ________ to overcome _______ ___ ______
A

3
Q
What happens in the Extrinsic Region?
A
Very few electrons cross
4
Q
What happens in the Intrinsic Region?
A
More Intrinsic electrons = Higher concentration, more phonons, and lower mobility
