Why relative permittivity of germanium is greater than that of diamond give reason?

∙ 8y ago
The relative permittivity of a material is a measure of how much the material can store electric potential energy. Germanium has a higher relative permittivity than diamond because germanium has more free charge carriers (due to its intrinsic semiconductor properties) that can contribute to the overall permittivity. In contrast, diamond is a pure covalent material with no free charge carriers, resulting in a lower relative permittivity.

Why relativity permittivity of germanium is greater than the diamond?
The relative permittivity (dielectric constant) of a material depends on several factors, including its atomic structure and bonding. Germanium has a higher relative permittivity than diamond because Germanium has a higher electron density and stronger electron-electron interactions, leading to a higher polarization of the material in an electric field compared to diamond. This results in a higher relative permittivity for Germanium.
Why germanium has larger leakage current than silicon?
Germanium has a smaller bandgap compared to silicon, leading to higher intrinsic carrier concentration and hence greater leakage current. Additionally, germanium has a higher intrinsic carrier mobility, which can further contribute to increased leakage current compared to silicon.
Why would you use silicon diodes instead of germanium?
Though germanium diodes were the first ones fabricated, several factors make silicon the choice vs. germanium diodes. Silicon diodes have a greater ease of processing, lower cost, greater power handling, less leakage and more stable temperature characteristics than germanium diodes. Germanium diodes' lower forward drop (.2V to .3V versus .7V to 1.0V) make them better at small signal detection and rectification.
What color does diamond streak?
Diamond does not streak. Anything with a Mohs hardness greater than about 7 will cut the ceramic plate used for the test. Diamond, the hardest naturally occurring substance, has a Mohs hardness of 10. (Nothing else in nature comes close.)
What is the relative density in water?
The relative density in water refers to how dense a substance is compared to water. If the relative density is greater than 1, the substance will sink in water. If the relative density is less than 1, the substance will float in water.

Why does germanium has greater first ionisation energy than gallium?
Germanium has a greater first ionization energy than gallium because germanium has a smaller atomic size and thus a stronger nuclear charge, making it more difficult to remove an electron. Additionally, the electronic configuration of germanium (4d^10 5s^2 5p^2) is more stable compared to gallium (4d^10 5s^2 5p^1), resulting in a higher ionization energy.
What is represented by 'A' in 'OA79' diode?
The symbol 'A' indicates that this device is made from germanium . as you may know germanium has less cut in voltage so this device is used for low power signal or for signal processing. also the leakage current or reverse saturation current of germanium is greater than silicon.
Why germanium shows good reducing properties?
because its size is big and hence have greater tendency to accept electrons.

Which has a greater ionization energy beryllium or germanium?
Beryllium has greater ionization energy, with 899 kJ/mol versus Germanium's 762 kJ/mol. The general trend (most prominently displayed in the representative elements) in the periodic table is increasing ionization energy across a period, and decreasing ionization energy down a group.
With a blood alcohol level at 15 percent the relative risk of causing a collision is greater by nearly?
whith a blood alcohol level at .15%, the relative risk of causing a collision is greater by mearly?
Which has the lower electron affinity germanium or selenium?
Selenium has a lower electron affinity than germanium. Electron affinity is the energy released when an atom gains an electron to form a negative ion. In general, electron affinity tends to decrease as you move down a group in the periodic table, which is why selenium has a lower electron affinity than germanium.
Does a diamond sparkle in water or in air?
A diamond sparkles more in air than in water due to differences in refractive indexes. The refractive index of diamond is higher than that of air, causing light to reflect more within the diamond and create a sparkly appearance. In water, the refractive index is closer to that of diamond, resulting in less sparkle.
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.
