There are several reasons why silicon is mostly used in the production of semiconductor devices compared to germanium:
1. Abundance: Silicon is the second most abundant element in the Earth's crust, making it more readily available and cost-effective compared to germanium.
2. Stability: Silicon is more stable at higher temperatures compared to germanium, making it more suitable for use in high-temperature applications.
3. Higher melting point: Silicon has a higher melting point than germanium, making it more durable and reliable for use in semiconductor devices.
4. Better thermal conductivity: Silicon has better thermal conductivity compared to germanium, allowing for better heat dissipation and overall performance of semiconductor devices.
5. Compatibility with modern technology: Silicon has been extensively researched and developed for use in semiconductor technology, making it more compatible with modern manufacturing processes and techniques.
Overall, silicon's abundance, stability, durability, thermal conductivity, and compatibility with modern technology make it a more preferred choice for the production of semiconductor devices compared to germanium.

Silicon is mostly used in the production of semiconductor devices compared to germanium for the following reasons:
1. Abundance and cost: Silicon is the second most abundant element in the Earth's crust, making it readily available and inexpensive. Germanium is a much rarer element, leading to higher production costs.
2. Electrical properties: Silicon has a higher bandgap energy than germanium (1.12 eV vs. 0.67 eV), which makes it less susceptible to thermal noise and leakage current at room temperature. This is critical for the stable operation of semiconductor devices.
3. Oxide stability: Silicon forms a highly stable, protective oxide (SiO2) layer when exposed to oxygen. This oxide layer acts as an insulator, reducing surface leakage and allowing for the creation of MOSFET (metal-oxide-semiconductor field-effect transistor) devices. Germanium oxide (GeO2) is less stable and prone to defects, making it a less suitable material for device fabrication.
4. Processing technology: Silicon has a more mature and well-developed fabrication technology compared to germanium. This includes techniques for crystal growth, doping, patterning, and oxidation, which are essential for producing high-quality semiconductor devices.
5. Compatibility with other materials: Silicon can be easily integrated with other materials, such as metal electrodes and dielectrics, forming reliable and durable contacts. This versatility allows for the creation of complex semiconductor devices with multiple components.
Due to these advantages, silicon has become the dominant material for the production of a wide range of semiconductor devices, including transistors, integrated circuits (ICs), solar cells, and sensors. Germanium is still used in some specialized applications, such as high-power devices and radiation detectors, where its higher carrier mobility and lower bandgap energy offer advantages.
