Sample EC8252 ELECTRONIC DEVICES Important Questions

1.What are semiconductors?
The materials whose electrical property lies between those of conductors and insulators
are known as Semiconductors. Ex germanium, silicon.
It has two types. EC8252 ELECTRONIC DEVICES Important Questions
1. Intrinsic semiconductor 2. Extrinsic semiconductor.
2.Differentiate between intrinsic and extrinsic semiconductor
Pure form of semiconductors are said to be intrinsic semiconductor.
Ex: germanium, silicon.
It has poor conductivity
If certain amount of impurity atom is added to intrinsic semiconductor the resulting
semiconductor is Extrinsic or impure Semiconductor
It has good conductivity.
3.Define drift current? EC8252 ELECTRONIC DEVICES Important Questions
When an electric field is applied across the semiconductor, the holes move towards the
negative terminal of the battery and electron move towards the positive terminal of the battery.
This drift movement of charge carriers will result in a current termed as drift current.
4.Give the expression for drift current density
Drift current density due to electrons
Jn = q n μnE
Where,
Jn – drift current density due to electron
q- Charge of electron

5.Define the term diffusion current?
A concentration gradient exists, if the number of either electrons or holes is greater in one
region of a semiconductor as compared to the rest of the region. The holes and electron EC8252 ELECTRONIC DEVICES Important Questions
tend to move from region of higher concentration to the region of lower concentration.
This process in called diffusion and the current produced due this movement is diffusion
current.
