DIODES
Electrical Device > Chip of semiconducting material doped with impurities to create a p-n junction. > Allows current to move through it in one direction. (One way valve).
pn-Junction > Boundary between n-type (Donor) and p-type (Acceptors) doped impurities.
Applications > Radio Modulation > Power Conversion > Over Voltage Protection > Logic Gates > Radiation Detectors > Temperature Measurements > Current Steering > Light Source (LED)
LED of Shapes &Sizes
LEDs > Small > Bright > Uniform illumination > Inexpensive > Easily Strobed > Low Temperature > Limited Wear & Tear > Different colors = Better Visibility > Synchronized with Imaging
