Silicon is known as a semiconductor. Conductors like copper or gold readily allow electricity to flow through them when voltage, which is electromagnetic force or pressure, is applied. Semiconductors act like a resistor (something that resists electrical flow no matter how much voltage is applied), however once a certain amount of voltage is applied (0.7 Volts in the case of Silicon), the semiconductor 'turns on' and allows electricity to pass as though it were a conductor.
What else can I help you with?
What is silicon conductivity?
Silicon is a semiconductor material that has moderate conductivity. Its conductivity can be increased by adding specific impurities through a process called doping. This makes silicon a key material for building electronic devices such as transistors and integrated circuits.
Silicon electrical conductivity?
Varies dramatically with dopant concentration. Pure silicon is almost an insulator.
How Significant is the Role of Doping in Semiconductor's Conductivity?
Very. Doping determines the conductivity, pure silicon is a good insulator.
Is silicon a good conductor at energy?
semi conductor. a good semi conductor. It can also be n or p doped to increase it's conductivity
Why is the electrical conductivity of pure silicon very low?
The electrical conductivity of pure silicon is very low because it is a semiconductor with a full valence band and an energy gap between the valence and conduction bands. In its pure form, silicon does not have enough free electrons to conduct electricity effectively. doping silicon with other elements can increase its conductivity.
Which element increases its electrical conductivity as its temperature increases?
The element that increases its electrical conductivity as its temperature increases is typically a metal, such as copper or silver. This behavior is due to more free electrons being available to carry electric current at higher temperatures, leading to an increase in conductivity.
What element shows moderate electrical conductivity?
Silicon is an element that exhibits moderate electrical conductivity. While silicon is generally known as a semiconductor, it can conduct electricity better than nonmetals such as insulators, but not as effectively as metals.
Is silicon a better conductor of electric current than silver is?
No, silicon is not a better conductor of electricity than silver. Silver is one of the best conductors of electricity due to its high electrical conductivity, surpassed only by materials like copper and gold. Silicon is a semiconductor and has lower conductivity compared to silver.
Is silicon nonconductor?
Silicon is a semiconductor, not a nonconductor. It lies in between conductors and nonconductors in terms of electrical conductivity. It is widely used in technology for its semiconductor properties.
What has the author G Busch written?
G. Busch has written: 'The electrical conductivity of silicon carbide'
How does doping alter the atomic structure of silicon?
It does not alter the atomic structure of the silicon at all, what it alters is the balance of bulk valence band and conduction band electrons in the crystal of silicon thus altering its bulk conductivity.
Why you do not take pure silicon and use extrinsic silicon material?
Extrinsic silicon is just silicon that has been doped. So it has different semiconducting propeties from pure (intrinsic) silicon. Why anyone needed to introduce the words intrinsic and extrinsic into the subject always baffled me.
