Why is silicon a better semiconductor than germanium?

Why is silicon a better semiconductor than germanium?

Why is Silicon preferred over Germanium for semiconductor? The reason is, Silicon can be worked at a higher temperature as compared to germanium. The structure of Germanium crystals will be destroyed at higher temperature. Also, Silicon has much smaller leakage current than that of germanium.

Why is silicon a better semiconductor?

Silicon prevailed because it has superior physical and technological properties compared to the other semiconductor materials. -Silicon is abundant in the earth crest as an ore in the form of quartizite, -There are effective extraction and purification methods of silicon from its raw material.

Which of the following is the advantages of Si over Ge?

Silicon is abundant on the earth’s surface and therefore cheaper than germanium. The PIV (Peak Inverse Voltage) rating of silicon is much higher than germanium and therefore can withstand much higher temperatures than germanium.

Is silicon a better conductor than germanium?

In solid state electronics, either pure silicon or germanium may be used as the intrinsic semiconductor which forms the starting point for fabrication. Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity.

Why Si is more popular over Ge in wafers?

Why is Silicon Better Than Germanium? Silicon crystals have fewer free electrons than germanium crystals at room temperature, which is why silicon crystals are used for semiconductor devices.

What is difference between silicon and germanium?

Silicon and germanium have four valence electrons but at the given temperature germanium will have more free electrons and higher conductivity than silicon. Silicon is more widely used in the electronic device than germanium since it can be used at a higher temperature.

Why silicon diode is better than germanium diode?

The main reasons for silicon diodes to be preferred over germanium diodes are: Silicon diode is easier to produce than germanium diode due to the widespread availability of silicon. The silicon diode is less sensitive than the germanium diode, hence the operation of silicon diodes is stable with changes in temperature.

What is the advantage of silicon?

Durable and reliable: Silicone is highly durable and retains its shape and flexibility in extreme conditions, making it a particularly reliable material for use in critical applications.

What are the differences between silicon and germanium semiconductor?

Silicon and germanium have four valence electrons but at the given temperature germanium will have more free electrons and higher conductivity than silicon. Silicon is more widely used in the electronic device than germanium since it can be used at a higher temperature. Was this answer helpful?

Is silicon a good conductor?

Silicon is a semiconductor, meaning that it does conduct electricity. Unlike a typical metal, however, silicon gets better at conducting electricity as the temperature increases (metals get worse at conductivity at higher temperatures).

Why Si is preferred over Ge for manufacturing most of the semiconductor devices explain each reason?

The structure of Germanium crystals will be destroyed at higher temperature. However, Silicon crystals are not easily damaged by excess heat. Peak Inverse Voltage ratings of Silicon diodes are greater than Germanium diodes. Si is less expensive due to the greater abundance of element.
