Principle & Mechanism

LED means and is one of many hardware terms in the TechTerms dictionary.

All definitions on the TechTerms website are written to be technically accurate but also easy to understand.

The essential portion of the Light Emitting Diode is the semiconductor chip.

Semiconductors can be either intrinsic or extrinsic. Intrinsic semiconductors are those in which the electrical behavior

the semiconductor is said to be extrinsic.

This chip is further divided into two parts or regions which are separated by a boundary called a junction.

Low power requirement

Most types can be operated with battery power supplies.

The p-region is dominated by positive electric charges

High efficiency

the n-region is dominated by negative electric charges (electrons).

Long life

The junction serves as a barrier to the flow of the electrons between the p and the n-regions.

. This is somewhat similar to the role of the band-gap because it determines
