LED FLASH

SEMICONDUCTORS

• Materials are silicon, germanium, gallium arsenide, silicon carbide
• Semiconductors are the main function part of the LED Flash
• Uses two semiconductors, the p-type and the n-type
• Attach them toghther and you get a weak insulation zone
• The zone prevents positive and negative charges combining

LED FLASH FINAL

• When the charges combine it forms holes
• The holes are what produces the flash
• The flash can be weak at times because it needs to be charged
• Batteries can also help charge the semiconductors
• When the LED is turned on, all of the electron-holes make a flash
