O K is absolute zero. At absolute zero, the electrons of the semi conductors are trapped and are immovable from their electron shell as they are in a low energy state. This makes the pure semiconductor an insulator. One must heat the semiconductor to give the electrons enough energy to move to free them from their electron shell, and thus conduct.

What is the temperature coefficient of an extrinsic semiconductor is?
positive
How will an electrical circuit behave if there is an open circuit?
The circuit is incomplete, you will have no continuity, no flow of current to the load or other components. The voltage across every component in the circuit is zero. No part of the circuit stores or dissipates any energy. In short, the circuit doesn't work.
Why is absolute zero important?
absolute zero is the essence of nothing and nothing is a quantity of zero.
What is the interlace in pole and zero?
its nothing but alternate occurence of pole/zero and zero/pole. ex: f(s)=s*(s+2)/(s+1). here we can easily sense that there is a occurence of zero(s=0),pole(s=-1),zero(s=-2).
Why frequency of DC current is zero?
frequency if it will not zero then we cant tell its dc ...AnswerFrequency is the number of alternations per unit time. As d.c. doesn't alternate, then zero divided by any quantity of time is zero!
Is graphene a semiconductor?
Graphene is not a semiconductor; it is a zero-gap semiconductor which means that it lacks an energy gap between the valence and conduction bands. This property makes graphene behave more like a metallic conductor rather than a traditional semiconductor.
Why pure semiconductor just behave like an insulator?
At absolute zero (0K), an intrinsic semiconductor will act like a perfect insulator. At this temperature, the electrons in the valence band will remain there. The heat energy required to excite the electrons from the valence band to the conduction band is insufficient at 0K. When the temperature increases, some of the electrons from the valence band got excited and moves to the conduction band. This will give rise to the conductivity of the semiconductor. i.e in 0 k(0 kelvin) the pure semi conductor the electrons in the valance band don't do any thing.They are lazy for conductivity.But when increasing the temperature increase the energy of electrons and they try to move.At the end electrons win and they can to move.So it happened a conductivity.
What is the difference in the electric field inside and outside a charged insulator?
The electric field inside a charged insulator is zero, while the electric field outside a charged insulator is non-zero.
Pn diode in zero bias condition?
dormant semiconductor
What is the temperature coefficient of an extrinsic semiconductor is?
positive
Why does current stop at absolute zero in a semiconductor?
At absolute zero, semiconductor atoms come to a stop due to lack of thermal energy, reducing the number of free charge carriers available for conduction. Without free charge carriers, current cannot flow through the semiconductor, resulting in the cessation of electrical conduction at absolute zero.
How semiconductors behaves at absolute temperature?
At absolute zero temperature, semiconductors behave as insulators because all energy levels are occupied and no electrons are able to move through the material. As temperature increases, electrons are excited to higher energy levels, allowing them to conduct electricity. This behavior is described by the semiconductor's band structure and can be manipulated by introducing impurities or applying an electric field.
Why p type semiconductor has majority charge carrier as hole?
The majority carrier in p-type semiconductor is the hole. Electron carriers in p-type semiconductor are minority carriers. Minority carriers in any semiconductor are produced mainly by heat. Only at absolute zero temperature would there be no minority carriers.
Does porcelain have a nearly zero temperature coefficient of resistance?
Porcelain is an insulator, its resistance approximates infinity.
Is pottery an insulator or a conductor?
Pottery is an insulator. Both electrical and thermal. However earthenware (low fired clays like brick) can be porous (liquids can penetrate it) and if the liquid is an electolyte (like salt water), certain electrical conduction can take place.
How do you neutralize a charged insulator?
A charged insulator can be neutralized by grounding it, which involves connecting it to the Earth's surface with a conductor. This allows the excess charges to flow away, leaving the insulator with zero net charge. Alternatively, you can also neutralize a charged insulator by introducing an opposite charge to cancel out the excess charges.
How do you behave like Takiya Genji?
To behave like Takiya Genji from the movie "Crows Zero," you may emulate his confidence, loyalty to friends, and leadership qualities. You can adopt his charismatic and fearless demeanor, prioritize teamwork, and stand up for what you believe in while maintaining a strong moral compass. Remember, it's important to stay true to yourself while being inspired by his attributes.
