Conductors, Semi-conductors, Insulators Flashcards
What is the material that allows electric charges to pass through easily?
Conductor
How many valence electrons are there in a conductor?
1
What is the relationship of conductivity and resistivity?
Inversely proportional relationship
How will you describe the separation between the valence and conduction band?
Overlap
What is the effect of temperature to a conductor?
Positive (as the temperature increases, the conductivity decreases)
What is the type of bond present in conductors?
Metallic bond
What is the material that may or may not allow electric charges to pass through?
Semi-conductor
What is the level of resistivity and conductivity in semi-conductors?
Moderate
How many valence electrons are there in semi-conductors?
4
By how many electron volt are the conduction and valence band separated to each other in semi-conductors?
1 eV
What is the charge carrier of semi-conductors?
Intrinsic (electrons, holes)
What do you call the material that does not allow electric charges to pass through?
Insulator
How would you describe the conductivity of an insulator?
Low
How many valence electrons are present in insulator?
8
By how many electron volt are the conduction and valence band separated in insulators?
6 eV
