Why sillicon is more popular than germenium?

Why is silicon usually preferred to germanium in the manufacture of semiconductor devices? 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.

Why silicon diode is more popular 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.

Is Silicon better 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 silicon is the best semiconductor?

Silicon is used because it can be used as either an insulator (doesn't allow electricity to flow) or a semiconductor (allows a little flow of electricity). This is important for making chips. Also, it is very, very cheap.

Why is silicon widely used?

Silicon is used for electronic devices because it is an element with very special properties. One of it's most important properties is that it is a semiconductor. This means that it conducts electricity under some conditions and acts as an insulator under others. ... Silicon is also an abundant element on Earth.

Why is germanium more temperature dependent than silicon?

Germanium is more temperature sensitive than silicon because it has a smaller band gap. Even at moderate temperature, a substantial number of electrons in germanium are produce from thermal generation. For example at about 120 C, the concentration of electrons and holes from thermal generation is > 1E15.

What is the difference between silicon and germanium?

Silicon is a chemical element with atomic number 14 and chemical symbol Si while germanium is a chemical element with atomic number 32 and chemical symbol is Ge. The key difference between silicon and germanium is that Germanium has d electrons, but Silicon does not have any d electrons.

Why silicon is used as substrate?

Silicon, a very common element, is used as the raw material of semiconductors because of its stable structure. Purification of Silicon consumes large amounts of power.

Why is silicon transistor more commonly used compared to germanium transistor?

Silicon as a semiconductor has wider bandgap than germanium and therefore it can be operated at a much higher temperature up to 120 degree centigrade . It interstice concentration is much less than Ge and therefore the reverse saturation current has much less values for Si which means less of currents.

Why silicon and germanium are the two widely used semiconductor materials?

Silicon and germanium are used here effectively because they have 4 valence electrons in their outermost shell, which gives them the ability to gain or lose electrons equally at the same time.

Why silicon is better than germanium semiconductor?

Why is silicon usually preferred to germanium in the manufacture of semiconductor devices? 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 germanium a better semiconductor than silicon?

Ge has higher electron and hole mobility and because of this Ge devices can function up to a higher frequency than Si devices. The germanium diode is also superior to silicon diode in terms of energy loss, current loss, etc. The Ge diode loses only 0.3-0.4 a volt while a silicon diode loses about 0.6-0.7 volts.

Why is silicon The most commonly used substrate for fabricating ICS?

Silicon dioxide is the most widely used insulator in IC technology owing to its extremely stable chemical nature when compare to other oxides like Germanium, which is water soluble and decomposes at a temperature of 800 degree Celsius.

What is the most widely used semiconductive material elaborate why it is the most widely used?

Silicon is the most widely used type of semiconductor material. Its major advantage is that it is easy to fabricate and provides good general electrical and mechanical properties.

Why are silicon and germanium useful in the electronics industry?

Explanation: Each has four valence electrons, but germanium will at a given temperature have more free electrons and a higher conductivity. Silicon is by far the more widely used semiconductor for electronics, partly because it can be used at much higher temperatures than germanium.

Why are germanium and silicon not efficient conductors?

Pure silicon and germanium are poor conductors of electricity because their outer electrons are tied up in the covalent bonds of the diamondlike framework. ... Electrical conductivity decreases as temperature increases in metals because the vibrations of the atoms make passage of electrons more difficult.

Is silicon sensitive to temperature?

The measured temperature sensitivities are 0.110 nm/°C at room temperature and 0.123 nm/°C with temperatures above 50°C. The temperature dependence for the air-cladded device is dominated by the TOC of silicon, showing similar results for both temperature ranges.
