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

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 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.


Would a diamond float or sink in mercury?

A diamond would sink in mercury because the density of a diamond (around 3.5 g/cm^3) is greater than that of mercury (around 13.5 g/cm^3), making the diamond denser than the liquid mercury.


Why does total internal reflection occur more in a diamond than in other gemstones?

Total internal reflection occurs more in a diamond than in other gemstones because diamonds have a higher refractive index, which causes light to bend more when passing through the diamond. This bending of light at the diamond's surface results in a greater likelihood of total internal reflection occurring within the diamond, leading to its characteristic sparkle and brilliance.

Will germanium sink or float in water?

Germanium has a density of about 5.32 g/cm³, which is significantly greater than the density of water (approximately 1 g/cm³). Therefore, germanium will sink when placed 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.


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.


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.


Why silicon prefer to germiniuam?

Four reasons. First, it is a LOT cheaper and easier to get silicon. Germanium is a trace element in rocks. You need to mine and process lots of rock to get any germanium. Silicon is also known as sand--very easy to find. Second, germanium is heat sensitive. It's harder to solder a germanium device in than a silicon one because the heat can mess up the germanium. Germanium devices pretty much have to be soldered in by hand because you have to heat sink them, whereas silicon devices can be soldered in a soldering machine. Third, germanium's hazardous and silicon is generally not. People eat off glass plates, which are made from silicon. They do NOT eat from germanium plates, if they could even afford them. And fourth, germanium has a variable voltage drop--the higher the voltage, the greater the drop. If you pump 5000 volts into a silicon diode, you're going to get 4999.3v out the other side.
