Germanium diodes have a lower forward voltage drop compared to silicon diodes, making them suitable for low voltage applications. However, they have higher leakage current and are more temperature sensitive. Silicon diodes, on the other hand, have higher forward voltage drop but are more stable over a wider temperature range and have lower leakage current.

Why silicon is preferred over germanium in the fabrication of p-n junction diode?
Silicon is preferred over germanium in the fabrication of p-n junction diodes because silicon has a higher bandgap energy, which allows for better temperature stability and leakage control. Silicon also has better electrical properties, such as higher breakdown voltage and lower intrinsic carrier concentration, making it more suitable for high-performance diode applications. Additionally, silicon is more abundant and cheaper to produce compared to germanium.
Why we can't use silicon and germanium in laser diode?
Silicon and germanium are indirect bandgap materials, which means they are not efficient in emitting light when an electric current passes through them. Laser diodes require direct bandgap materials such as gallium arsenide or indium phosphide, which are more efficient in converting electrical energy into light.
Is the organic germanium Sesquioxide Ge-132 the same that's used in diodes?
No, the organic germanium compound Ge-132 (germanium sesquioxide) is used as a dietary supplement and in some alternative medicine practices. Germanium diodes, on the other hand, typically use inorganic germanium semiconductors for their electronic properties in devices like radios and amplifiers.
A semiconductor can be made by adding atoms of other elements to?
A semiconductor can be made by adding atoms of other elements to a pure semiconductor material, such as silicon or germanium. By selectively adding specific impurity atoms (dopants), the conductivity of the semiconductor material can be controlled, making it suitable for use in electronic devices like transistors and diodes.
Why are metalloids used in the electronic goods industry?
Metalloids such as silicon and germanium are used in the electronic goods industry because they exhibit properties of both metals and nonmetals. They are semiconductors, which means they can conduct electricity under certain conditions. This property is essential for the fabrication of electronic components like transistors and diodes.
What is the difference of silicon diode and germanium diode?
Silicon diodes have higher forward voltage drop, lower reverse leakage current, and higher operating temperature compared to germanium diodes. Germanium diodes have lower forward voltage drop and higher reverse leakage current compared to silicon diodes.
Diodes and transistors are made of semiconductor material such as germanium and what?
Silicon
What is the temperature of germanium diode compare to silicon diode?
Germanium diodes typically have a lower forward voltage drop than silicon diodes, which can result in slightly higher temperatures under the same operating conditions. However, the difference in temperature between the two types of diodes is generally minimal and may vary depending on the specific application.
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.
Is 1N4007 OA79 silicon or germanium diode?
The entire 1N40xx series of power diodes are all silicon. The OA79 small signal diode is germanium.
What parameter in a germanium diode differs from those in a silicon diode?
A germanium diode has a lower forward voltage drop compared to a silicon diode, typically around 0.3V for germanium and 0.7V for silicon. Germanium diodes also have a higher reverse current leakage compared to silicon diodes.
What is the difference between a silicon diode and germanium diode?
Silicon diodes have a higher forward voltage drop (~0.7V) compared to germanium diodes (~0.3V). Silicon diodes have higher temperature stability and are more commonly used in modern electronic devices, while germanium diodes are more sensitive to temperature changes and are less commonly used.
What is the difference between a silicon diode and a germanium diode?
The main difference between a silicon diode and a germanium diode is the forward voltage drop. Silicon diodes have a higher forward voltage drop (around 0.7V) compared to germanium diodes (around 0.3V). Additionally, silicon diodes have better temperature stability and higher reverse breakdown voltage compared to germanium diodes.
Why cut in voltage of silicon is more than that of germanium?
Silicon has a larger band gap energy than germanium, resulting in a higher cut-in voltage for silicon diodes compared to germanium diodes. The larger band gap in silicon means that it requires more energy for electrons to be excited into the conduction band, resulting in a higher cut-in voltage.
What is more referred to use si diode or a ge diode?
Silicon (Si) diodes are more commonly used than germanium (Ge) diodes. Silicon diodes are preferred for most applications due to their higher temperature tolerance, lower leakage current, and greater availability. They are commonly used in rectifiers, signal processing, and various electronic circuits. Germanium diodes, while having some advantages in specific applications (such as lower forward voltage drop), are less common in modern electronics.
What is the threshold voltage of silicon and germanium?
In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.
What is the cut in voltage of GE and SI diodes?
for germanium it is 0.3 and for silicon it is 0.7
