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 else can I help you with?
Is tungsten a semiconductor?
No, tungsten is not a semiconductor. Tungsten is a metal known for its high melting point and resistance to corrosion. Semiconductors are materials that have conductivity between that of a conductor and an insulator, like silicon or germanium.
What is a material that has resistance in between a conductor and an insulator?
A semiconductor is a material that has resistance in between a conductor and an insulator. This means that it can conduct electricity under certain conditions but acts as an insulator under others. Examples include silicon and germanium.
Is Hydrogen a conductor or insulator?
Hydrogen is an insulator if it is not ionized. Like any other gas, if a high voltage is applied, electrons separate from the nucleus, creating a plasma, which does conduct. Some experimental fusion generators use hydrogen plasma.
IS A WOODEN STICK AN INSULATOR OR CONDUCTOR?
A wooden stick is considered an insulator because wood is a poor conductor of electricity. It does not allow electricity to flow easily through it like a conductor would.
Is sulfur a good insulator of electricity?
Sulfur is not a good insulator of electricity. It is a poor conductor of electricity, like rubber or wood. If you need a material for insulating against electricity, consider using materials like plastic or glass instead.
What is the difference between semiconductor and electronics?
A semiconductor is a device which is neither a Insulator nor a conductor. They behave like one in the right conditions.
Can a semiconductor be made to become a conductor or an insulator?
Yes, a semiconductor can be made to behave as a conductor or an insulator by controlling the amount of impurities added to it. Adding impurities through a process called doping can change the conductivity of the semiconductor material, making it act like a conductor or an insulator.
Is boron likely to be an insulator?
No, boron is not likely to be an insulator. It is a metalloid with properties that are in between those of metals and nonmetals, so its conductivity can vary. Pure boron tends to behave more like a semiconductor rather than an insulator.
Why the semiconductor behave like a insulator as a zero?
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 a semi insulator?
A semi-insulator is a material that exhibits properties of both a semiconductor and an insulator. It has a very high resistance to the flow of electric current, similar to an insulator, but can conduct electricity under certain conditions, like a semiconductor. Common examples include gallium arsenide and silicon carbide.
Is lead conductor semi conductor or insulator?
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
Is germanium a insulator?
No, germanium is a semiconductor material, not an insulator. It has electrical properties that are in between conductors (like metals) and insulators (like nonmetals), making it useful for various electronic applications.
Is tungsten a semiconductor?
No, tungsten is not a semiconductor. Tungsten is a metal known for its high melting point and resistance to corrosion. Semiconductors are materials that have conductivity between that of a conductor and an insulator, like silicon or germanium.
What is a material that has resistance in between a conductor and an insulator?
A semiconductor is a material that has resistance in between a conductor and an insulator. This means that it can conduct electricity under certain conditions but acts as an insulator under others. Examples include silicon and germanium.
What is the intermediate between a conductor and a insulator?
A semiconductor is the intermediate material between a conductor and an insulator. It has electrical conductivity between that of a conductor and an insulator and can be controlled by factors like temperature or impurities. Semiconductors are widely used in electronic devices such as transistors and diodes.
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.
Is metal a semiconductor or insulator?
Most metals are conductors. A semiconductor is a non-metal material like silicon or germanium which is'doped' with another substance to give the material either a surplus of outer-shell electrons, or a deficiency of them.
