The depletion region in germanium is small because germanium has a lower band gap compared to silicon. This results in a higher charge carrier concentration and a narrower depletion region. Additionally, germanium has a higher intrinsic carrier concentration, leading to a smaller depletion region.
What else can I help you with?
Why depletion region is small in germanium compared to silicon?
The depletion region is smaller in germanium compared to silicon because germanium has a lower bandgap energy, meaning that charge carriers can easily cross the depletion region and recombine on the other side. This results in a smaller built-in potential and a smaller depletion region in germanium.
Where was germanium found?
Germanium was first discovered in a rare mineral called argyrodite, which was found in the Himmelsfürst mine, Germany. It is also found in small amounts in various minerals like germanite, argyrodite, and zinc ores.
The Maximum spectral response of the germanium and silicon is in the X-ray region?
The maximum spectral response of germanium and silicon is in the infrared region, not the X-ray region. Both materials are commonly used in infrared sensing applications due to their sensitivity in this range of the electromagnetic spectrum. X-rays are typically detected using materials such as cadmium telluride or mercury cadmium telluride.
How do humans get germanium?
Germanium is primarily extracted from the by-products of zinc ore processing, as well as from coal ash. It can also be found in small quantities in certain minerals like germanite. Once extracted, germanium is purified through a series of chemical processes to produce high-purity germanium for commercial use.
What is the band gap of germanium?
.3 ev

The Maximum spectral response of the germanium and silicon is in which region?
ultraviolet region
Is germanium a plant?
Yes. Germanium is a mineral. Small amounts of organic germanium are found in some plant-based foods.
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.
Is deplition of resourceis good?
No
Is the greenhouse effect made worse by the deplition of the ozone?
Yes, it is. The greenhouse effect is made worse by ozone deplition.
The Maximum spectral response of the germanium and silicon is in the?
The maximum spectral response of germanium is in the infrared region, while the maximum spectral response of silicon is in the visible light region. Germanium has a broader spectral response range compared to silicon.
The Maximum spectral response of the germanium and silicon is in the X-ray region?
The maximum spectral response of germanium and silicon is in the infrared region, not the X-ray region. Both materials are commonly used in infrared sensing applications due to their sensitivity in this range of the electromagnetic spectrum. X-rays are typically detected using materials such as cadmium telluride or mercury cadmium telluride.
Where on the planet is germanium found?
Germanium can be found in small quantities in coal deposits worldwide. It is also found in some zinc ores, such as sphalerite. Germany, Russia, and the United States are some of the main producers of germanium.
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
How germanium naturally occurs?
Germanium is mainly found in minerals like germanite, argyrodite, and germanium oxide in small quantities. It is primarily extracted as a byproduct of zinc ore processing and is also found in coal deposits. Germanium can also be found in trace amounts in some living organisms.
