Flashcards in Properties of semi intrinsic semi conductors Deck (6):
1

1-

Some electrons are able to jump the forbidden gap to enter the conduction band

2

2-

Electrons in the conduction band act as negative charge carriers

3

3-

The vacancies left behind in the valence band by the electron entering the conduction are known as holes
Holes behave like positive charges in the valence band

4

4-

Lattice vibrations increases as temperature increases

5

5.

Any effect due to increase in the number of charge carriers outweighs any effect due to an increase in lattice vibrations

6

6-

Overall resistance decreases as temperature rises
