Define What Is The Mechanism By Which Conduction Takes Place Inside The Semiconductor? |
|
Answer» Conduction occurs in any given material when an APPLIED electric field causes electrons to MOVE in a desired direction within the material. This may be due to one or both of two processes, electron motion and whole transfer. In case of FORMER process, free electrons in the conduction band move under the influence of the applied electric field. Hole transfer involves electrons which are still attached to the atoms i.e. those in VALENCE band.
