Optoelectronic Devices Flashcards
Is one of the fastest emerging technology fields that deals with applying electronic devices to the sourcing, detection and control of light.
Optoelectronics
Deals with the study and application of electronic devices that interacts with light which might be detection of light, its creation, and exploitation for several purposes
Optoelectronics
In this process, light is directly converted into electricity
Photoelectric or Photovoltaic
A material is made more electronically conductive by this electrical phenomenon
Photoconductivity
In this process, an energized molecule is made to interact with a light photon
Stimulated Emission
Approach where electron transfer occurs in semiconductors from valence to conducting band.
Radiative Recombination
Types of Optoelectronic Devices
Photodiode
Solar Cells
Light Emitting Diodes
Optical Fiber
Laser Diodes
Is a semiconductor light sensor that generates a voltage or current when light falls on the junction
Photodiode
Is created when a photon with plenty of energy strikes a semiconductor.
Electron or Hole Pair
Is formed when electrons diffuse to the junction of the photodiode
Electrical Field
The method in which the electric field of a photodiode across the depletion zone is equal to a negative voltage across the unbiased diode.
Inner Photoelectric Effect
An electronic device that directly converts sun’s energy into electricity.
Solar Cells
Is composed of photons that radiate from the sun.
Sunlight
A P-N semiconductor diode in which the recombination of electrons and holes yields a photon.
Light-Emitting Diode (LED)
Effect in which electrons recombine with the holes within the device and release energy in the form of photons.
Electroluminescence
