Electronic bands/conduction - islam Flashcards
1
Q
What is the valence band?
A
The highest occupied band.
2
Q
What is the conduction band?
A
A partially filled band that causes electrical conductivity.
3
Q
What is the highest filled energy level in a metal called?
A
The Fermi level.
4
Q
What happens to conductivity of metals as temperature increases?
A
Conductivity decreases due to thermal atomic vibrations and electron scattering.
5
Q
How does conductivity change with increasing temperature in semiconductors?
A
Conductivity increases due to a greater population of electrons in the upper conduction band.
6
Q
Is diamond an insulator, conductor or semiconductor?
A
Insulator.
