What does doled mean?
What does doled mean?
doled, dol·ing, doles. To give out, especially in portions or shares; allot or distribute. Often used with out: The mayor doled out jobs to those who had supported him in the election. See Synonyms at distribute.
What does doped out mean?
dope out (something) To solve or figure out; to calculate or infer from available information. We doped out a way of keeping the business open without having to fire anybody.
What does it mean to be doped?
Doping basically means athletes taking illegal substances to make their performance better. There are five types of banned drugs, called doping classes. The most common are stimulants and hormones.
What is meant by heavily doped?
heavily doped means more concentration of the charge carriers, which causes the increase in conductivity and hence becomes metallic like characteristics.
Why zener diode is highly doped?
The Zener diode, however, is heavily doped, as a result, they have a thin depletion region. Zener diode, under forward bias condition, conducts like a normal diode and if the applied voltage is higher than the reverse voltage then it conducts in the reverse bias condition too.
Is photodiode heavily doped?
The p-type and n-type semiconductors are heavily doped. Therefore, the p region and n region of the PIN photodiode has large number of charge carriers to carry electric current. Therefore, majority carriers will not carry electric current under reverse bias condition.
Why photodiode is heavily doped?
This photodiode uses an intrinsic semiconductor layer (N-doped or sometimes slightly doped) between the P and N layers, which has the effect of reducing the PN junction capacitance and thereby increasing the maximum switching speed, especially for fiber optic communication.
Is led heavily doped?
The light emitting diode (LED) is a heavily doped p-n junction with forward bias. It is a specially designed forward-biased p-n junction diode which emits light spontaneously when energised.
Is photodiode reverse biased?
A photodiode is designed to operate in reverse bias.
Why are photodiodes reverse biased?
The photodiode is reverse biased for operating in the photoconductive mode. As the photodiode is in reverse bias the width of the depletion layer increases. This reduces the junction capacitance and thereby the response time. In effect, the reverse bias causes faster response times for the photodiode.
What happens when LED is reverse biased?
An LED is a light emitting diode. The LED emits light when it is forward biased and it emits no light when it is reverse biased. The intensity of light is proportional to the square of the current flowing through the device.
What is the LEDs of SI?
A light-emitting diode (LED) is a semiconductor light source that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.
What purpose does the LED serve?
Recent advances in LED technology have made it possible for LEDs to produce white light as well. LEDs are commonly used for indicator lights (such as power on/off lights) on electronic devices. They also have several other applications, including electronic signs, clock displays, and flashlights.
