What is DIAC? - Symbol, Construction, Operation and Applications A diac is an important member of the thyristor family and is usually employed for triggering triacs. A diac is a…
What is Thyristor? - Thyristor Family and its Applications Thyristor is the general name given to a family of semiconductor devices having four layers with a control mechanism, although this…
Junction Field Effect Transistor (JFET) - Construction, Symbols and Operation: Depending upon the majority charge carriers, Junction Field Effect Transistor (JFET) have been classified into two types, namely (i) N-channel…
Various Bias Compensation Methods: During the discussion made for various biasing methods for providing stability to the operating point we have seen that self bias (or potential divider bias) and…
Light Emitting Materials: Since the eye is only sensitive to light of energy hf ≥ 1.8 eV (~ 0.7 μm), semiconductors of interest must have energy band gaps larger than this…
Photodetectors - Definition and Applications: Photodetectors are the semiconductor devices that can detect optical signals through electronic processes. The extension of coherent and incoherent light sources into the far-infrared region…
Luminescence - Definition and Types: When a system absorbs energy in some form or other, it may be partly re-emitted as radiation. This phenomenon is called luminescence. Luminescence may occur…
What is Optoelectronic Devices? Optoelectronics is the technology that combines optics and electronics and the devices based on this technology are known as optoelectronic devices. These devices include emitters, sensors…
