Examples of diode in the following topics:

  • Radiation Detection

    • When these detectors' sensitive structures are based on single diodes, they are called semiconductor diode detectors.
    • When they contain many diodes with different functions, the more general term "semiconductor detector" is used.

  • Using Interference to Read CDs and DVDs

    • The data is stored either by a stamping machine or laser and is read when the data is illuminated by a laser diode in the disc drive.

  • Implications of Quantum Mechanics

    • The study of semiconductors led to the invention of the diode and the transistor, which are indispensable parts of modern electronic systems and devices.

  • Ohm's Law

    • An example is the p-n junction diode.
    • The I–V curves of four devices: two resistors, a diode, and a battery.

  • Dosimetry

    • The equipment used in radiotherapy (a linear particle accelerator in external beam therapy) is routinely calibrated using ionization chambers or the new and more accurate diode technology.
