Conduction mechanism of semiconductor under influence of magnetic field
Answers
Conduction mechanisms in semi conductor refer to the means by which electronic charges moves through semiconductor under external stress particularly under the influence of an magnetic field.
In order to understand the conduction mechanism in semiconductor , it is necessary to first introduce the concept of band theory , which is well established in solid - state physics .
In general solid are made of atoms , each of which composed of a positively charged nucleus surrounded by negatively charged electrons .
In mechanical terms of quantum, these electrons effectively reside in discrete energy states in orbit .
When a large no. Of atoms are brought together to form a solid, the discrete energy States are so close together that energy bands began to form .
At the same time , there will be the gap between energy bands which are known as band gaps .
