The advantages of Si over Ge are:
=> Stable and strong material & crystal structure like diamond
=> Si has a wider bandgap than Ge
=> higher operating temperature (125-175 oC vs. ~85 oC) and thus become intrinsic at higher temp.
=> Si readily forms a native oxide (SiO2) high-quality insulator protects and "passivates" underlying circuitry helps in patterning useful for dopant masking.
=>Large variety of process steps possible without the problem of decomposition (as in the case of compound semiconductors)
=> Si is cheap and abundant
Silicon has a higher melting point and is more abundant, making it more cost-effective. Additionally, silicon dioxide forms a natural protective layer on the surface of silicon, which improves its stability. Silicon-based technology is more mature and widely adopted compared to germanium.

Why silicon is the more semiconductor than germanium?
Silicon is a more popular semiconductor than germanium due to factors such as its wider band gap, higher thermal stability, and better abundance in nature. Silicon also has better manufacturing processes and can operate at higher temperatures, making it more suitable for a wide range of electronic applications.
Why is silicon a better semiconductor than germanium?
Silicon has a higher operating temperature and better thermal stability compared to germanium, making it more reliable for electronic devices. Additionally, silicon's oxide layer forms a better insulating material for integrated circuits, enhancing its performance. Silicon also has a wider bandgap than germanium, allowing for better control of electrical conduction.
Why silicon is prefer in semiconductor as compare to germanium?
Silicon is preferred over germanium in semiconductor applications because it has a higher melting point, better thermal stability, and can form a native oxide layer for insulation. Additionally, silicon has a wider bandgap, making it more suitable for high-temperature and high-power electronic devices.
Which is a better semiconductor silicon or germanium?
Silicon is generally considered a better semiconductor than germanium due to its higher melting point, wider operating temperature range, and superior thermal conductivity. Silicon is also more abundant and less prone to electrical leakage compared to germanium.
What is difference between silicon and germanium semiconductors?
Silicon has a higher operating temperature and greater thermal stability compared to germanium. Silicon has a larger bandgap energy which makes it better suited for high-power applications. Germanium has a higher electron mobility which can result in faster transistors, but it is less commonly used in modern semiconductor devices.

What conducts electricity better germanium aluminum or helium?
Germanium conducts electricity better than aluminum or helium. Germanium is a semiconductor material with moderate conductivity, while aluminum is a metal with higher conductivity. Helium is a non-metal and is a poor conductor of electricity.
What material conducts electric current better than insulator but not as was as a conductor?
A semiconductor, such as silicon or germanium, fits this description. Semiconductors have electrical conductivity between that of insulators and conductors. They can be controlled to switch between conducting and insulating states, making them essential for modern electronics.
What is the definition of semicondutor?
A semiconductor is a material that has electrical conductivity between that of a conductor and an insulator. It can conduct some electrical current when a voltage is applied, but not as freely or efficiently as a conductor. Semiconductors are widely used in electronic devices such as transistors, diodes, and integrated circuits.
Why we don't we use iron as a semiconductor?
Iron is not typically used as a semiconductor because its electronic properties make it better suited as a conductor. Additionally, iron's crystalline structure does not easily allow for the manipulation of its electrical conductivity to the extent required for use as a semiconductor in electronic devices. Other materials such as silicon and gallium arsenide are more commonly used for semiconductors due to their superior electronic properties.
Why do you use silicon as semiconductor instead of germanium?
Silicon is more abundant, less costly, and can withstand higher temperatures compared to germanium. Silicon also forms a better oxide layer, which is important for creating reliable semiconductor devices. Additionally, silicon has higher mobilities and lower intrinsic carrier concentration, making it more practical for various applications.
Is germanium a conductor of heat?
Germanium is a semiconductor, it means that electrons are relatively strongly attached to nuclei. As result its thermal properties change. Generally semiconductors have worse thermoconductivity than metals but better than insulators.
Which element is a semi-conductor of electricity?
Most conductors conduct both heat and electricity well. A semiconductor is a conductor whose resistance is between that of a conductor and an insulator. An example of a semiconductor is silicon which is used in electronic appliances
