Are lighter
Experience collision less frequently
Have negative charge
Need less energy to move them
Answer is Right!
Answer is Wrong!
The correct answer is: A. Are lighter
Conductivity is the ability of a material to carry an electric current. It is determined by the number of charge carriers (electrons or holes) and their
mobility. Mobility is the ease with which charge carriers can move through a material.Electrons are lighter than holes. This means that they have a higher velocity and can move through
a material more easily. As a result, electrons have a higher mobility than holes.The other options are incorrect because:
- Option B: Electrons and holes experience collisions with the atoms and other electrons in the material. The number of collisions does not affect the mobility of the charge carriers.
- Option C: The charge of the charge carrier does not affect its mobility.
- Option D: The energy required to move a charge carrier does not affect its mobility.
In conclusion, conduction band electrons have more mobility than holes because they are lighter.
