how that a temperature rise of 4k would raise the conductivity (i.e. the number of electrons in the conduction band) by 30%.

Sagot :

With the rise in temperature,the conductivity also increases.

With rising temperatures, semiconductors' electrical conductivity rises. The conductivity rises as a result of free mobility between the two bands created when electrons from the valence band are able to jump to the conduction band when the temperature rises.

Electrical Conductivity (EC), which is often expressed in Siemens (S) per distance, gauges a material's capacity to transfer an electrical current over a specific distance (usually m-meter). A conductivity meter is used to determine the conductance and read the electrical charge.
