An Intiative by Sri Chaitanya

At 0K temperature valance band electrons break away

At 0K in the crystal lattice of intrinsic semi conductors atoms form bonds with neighboring atoms which results in valence electrons being loosely bound

As temperature increases , covalent bond between atoms break and electrons in the valence band get energy and jump into the conduction band . This creates a hole in the valence band.

External electric field is the reason for the formation of holes

Detailed Solution

Rise in temperature causes electrons to jump from valance band to conduction band by breaking bonds between the atoms. As the electron jumps into the conduction band , a hole is created in the valance band.
