PPT-Lecture 16 Light Emitting Diodes

1 Recap When a currentcarrying semiconductor or metal is kept in a magnetic field the charge carriers of the semiconductor experience a force in a direction perpendicular to both the magnetic field and the current At equilibrium a voltage appears at the .

Light Emitting diodes are a semiconductor light source that emit light when the PN-junction is activated. This presentation will explain how LEDs are made, the materials that they are made out of, the structure that makes them what they are, and how the light that they create is used. .
