A Light-Emitting Diode is a semi-conductor based form of Electroluminescence.
It is built by taking a 'silicon wafer' (a thin slice ofpure silicon) and adding
special materials to parts of the silicon using a process called "doping".
This changes the electrical This1 properties of the silicon and current can
flow in one direction only. |
