What is the Conductivity of Semiconductor?
Conductivity Definition
The conductivity of a semiconductor is defined as its ability to conduct electricity, which is moderate due to its intermediate free electron concentration.
Role of Electrons and Holes
In semiconductors, both free electrons and holes act as charge carriers, enabling electrical conduction.
Temperature Effects
Conductivity of semiconductors increases with temperature because higher temperatures generate more free electrons and holes.
Energy for Bond Breaking
The energy needed to break covalent bonds in semiconductors, releasing electrons and creating holes, is crucial for understanding their conductivity.
Applications of Conductivity
The temperature sensitivity of semiconductors is useful for creating devices like thermistors that measure temperature changes
