)silicon has got less leakage current
2)high threshold voltage (to avoid unwanted triggering of the device from noise)
3)more adhesive to aluminum
The most commonly used metal as a semiconductor is silicon. Other metals that can be used as semiconductors include germanium and gallium arsenide. These materials have unique electronic properties that make them useful in electronic devices like transistors and diodes.
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.
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.
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.
The knee voltage for silicon is approximately 0.7V, while for germanium it is around 0.3V. The knee voltage is the voltage at which a diode starts conducting significantly.
Silicon and Germanium are often seen in transistors.
Yes, germanium was the only material used in transistors from when they were invented in 1947 until 1954 when the first successful silicon transistor was made. However the use of germanium still dominated transistors until the silicon mesa transistor was made commercially available by Fairchild Semiconductor in 1958. Development of the silicon planar transistor by Fairchild Semiconductor the next year ultimately made the integrated circuit possible. While almost all transistors today are silicon, there are still uses for germanium transistors so a few types are still made.

Silicon and Germanium are the elements used in transistors
The class of materials that make up transistors is "semiconductor." A transistor is often made from very pure silicon that is doped with germanium or other dopant to change its electrical properties.

You can consider using the silicon transistor 2N3904 as an equivalent for the AC128. The 2N3904 is a general-purpose NPN transistor commonly used in various amplifier and switching applications. Remember to check datasheets and specifications to ensure compatibility with your circuit requirements.
A transistor is mainly composed of silicon and germanium
Transistors are typically composed of three layers of either silicon or germanium semiconductor material: the emitter, the base, and the collector. The junctions between these layers determine the transistor's behavior as an amplifier or a switch. By controlling the flow of electric current between these layers, transistors can amplify or switch electronic signals.
