Why are some semiconductor materials suitable for optoelectronic devices explain?
Semiconductors can be Insulators • If the material is pure semiconductor material like silicon, the crystal lattice structure forms an excellent insulator since all the atoms are bound to one another and are not free for current flow.
Is a transistor an optoelectronic device?
Since the input signal intensity may be weaker than that of the source, an optical transistor amplifies the optical signal. The device is the optical analog of the electronic transistor that forms the basis of modern electronic devices.
What are optoelectronic devices and classify them?
Optoelectronics device is basically an electronic device involving light. Examples of optoelectronic devices include telecommunication laser, blue laser, optical fiber, LED traffic lights, photo diodes and solar cells.
What are optoelectronic devices?
This academic field covers a wide range of devices including LEDs and elements, image pick up devices, information displays, optical communication systems, optical storages and remote sensing systems, etc. Examples of optoelectronic devices include telecommunication laser, blue laser, optical fiber, LED traffic lights, photo diodes and solar cells.
How do semiconductor optoelectronic devices work?
Most semiconductor optoelectronic devices are pn-junction diodes, and their performance depends on the properties of the pn-junction and of the semiconductor material. To better describe the operation of laser diodes, LEDs. photodiodes, etc., it is necessary to understand the basics of the processes involved.
Why are pn-homojunctions still used in LEDs?
A pn-homojunctions (as well as pn-heterojunctions) is still used in LEDs emitting red or yellow light because it is easy to fabricate. The light originating in the spontaneous emission process is emitted from the light-emitting region (active layer) in all directions.
