Why germanium is better than silicon?
products made by silicon are more stable than those made by germanium
Why is germanium more metallic than silicon?
Germanium has a smaller band gap compared to silicon, allowing it to conduct electricity more effectively. Its crystal structure also has a closer packing arrangement of atoms compared to silicon, making it more metallic in nature. Overall, these factors contribute to germanium exhibiting more metallic properties than silicon.
Why silicon has low leakage of current as compared to germanium?
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 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 you prefer silicon atom as compared to germanium atom?
Silicon is preferred over germanium because it is more abundant, less costly, and has a higher thermal stability. Silicon also forms a better oxide layer, making it more suitable for integrated circuit applications. Additionally, silicon has better electron mobility and is less susceptible to thermal runaway compared to germanium.
Why germanium has less barrier potential than silicon?
germanium has great intrinsic concentration at room temperature,hence conduction is great in germanum compared to silicon, and resistance decreases in germanum and hence built in potentail also less in germanum compared to silicon.built in potential of silicon is 0.7v built in potential of germanum is 0.3v. 1)intrinsic concentration of germanium at room temperature is 2.5*10^13 atoms/cm^3. 2)intrinsic concentration of silicon at room temperature of 300k is 1.5*10^10 atoms/cm^3.
Why silicon potential barrier is higher?
The potential barrier in silicon is higher due to its relatively larger energy bandgap compared to other materials, such as germanium. This bandgap, approximately 1.1 eV for silicon, requires more energy to excite electrons from the valence band to the conduction band, thus creating a larger potential barrier for charge carriers. Additionally, silicon's crystal structure and doping levels influence the height of the potential barrier, affecting charge transport properties in semiconductor devices.
What has more shells or rings germanium or silicon?
germanium
What is the value of the barrier potential for a germanium diode at different temperatures?
The barrier potential of a germanium diode typically decreases with increasing temperature due to the increase in intrinsic carrier concentration. At room temperature (around 300K), the barrier potential is usually around 0.3-0.4V for a germanium diode.

Overall, these factors contribute to germanium exhibiting more metallic properties than silicon.
Why leakage current of germanium is more than silicon?
The higher leakage current in germanium compared to silicon is mainly due to its lower bandgap energy, which allows more thermally generated carriers to flow through at room temperature. Additionally, germanium has lower electron mobility and higher intrinsic carrier concentration than silicon, contributing to increased leakage current.
Why the temperature sensitivity of silicon is less than germanium?
The temperature sensitivity of silicon is less than germanium because silicon has a wider energy band gap than germanium. This wider band gap allows silicon to operate more efficiently at higher temperatures, resulting in less temperature-dependent changes in its electrical properties compared to germanium. Additionally, silicon has a higher thermal conductivity than germanium, which helps dissipate heat more effectively, reducing temperature effects on its performance.
