What is baising in electronic circuits?
Biasing means providing a voltage that overcomes or restricts the flow of carrier in semiconductor. No current will flow when any semiconductor is ubiased
Does drift current depends on carrier concentration?
no,drift current depends upon electric field where as carrier concentration lead to diffusion current
What material conducts electric current better than an insulation but not as well as a conductor?
semiconductor
What material conductors electric current better than an insulator but not as well a conductor?
semiconductor
What is the definition of electronics engineering?
electronics engineering is the branch of engineering which deals with the flow of current in a semiconductor devices/components. Semiconductor devices/components are those element which made from semiconductors like silicon germanium GaAs and other material. they are widely using in current generation.
Why silicon has low leakage of current as compared to germanium?
Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity. Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher temperatures than germanium.
Why FET is called as a unipolar transistor?
The FET is a semiconductor device with the output current controlled by an electric field. Since the current is carried predominantly by one type of carriers, the FET is known as a unipolar transistor.
How does Si diode work?
Crystal diode for a p-type semiconductor and n-type semiconductor formation of the pn junction, in its interface on both sides of a space-charge layer, and has a self-built electric field. When there is no applied voltage, as pn junction on both sides of carrier concentration caused by the proliferation of poor self-built electric current and drift arising from the current equivalent and the balance of power in the state. When the outside world a positive bias voltage, electric and outside the field of mutual self-suppression role of the Consumers carrier increase from the current spread of the forward current. When the outside world a reverse bias voltage, external electric field and to further strengthen self-built electric field, in a certain form of reverse voltage and reverse bias voltage value unrelated to reverse saturated current I0. When the reverse voltage applied to a certain high level, pn junction in the space charge of the electric field strength to achieve the critical values of the double-carrier process, a large amount of electronic hole right, had a great numerical breakdown of the reverse current, Breakdown phenomenon known as diodes.
What has the author Herbert Baldus written?
Herbert Baldus has written: 'The effect of cathode sputtering under high vacuum on the rectification effect of germanium' -- subject(s): Electric current rectifiers, Germanium
Materials of solar power?
In a crystalline solar electric panel, the light of the sun interacts with a semiconductor material (usually silicon) in the PV cell to free electrons and produce an electric current.
What does LED stand for in relation to light?
LED = Light-Emitting Diode This is a semiconductor diode that emits light when an electric current is applied in the forward direction of the device.
What is forward bias current in semiconductor?
I think its related to junction of two dissimilar semiconductor (or semiconductor and metal) and not only a semiconductor. well when two opposite nature semiconductor (hetero or homo) are joined to form a junctions they allow the flow of current in one direction while blocks it in other direction. The applied bias V which will cause the current flow is called forward bias and the current flowing through the junction forward bias current.
