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.
What else can I help you with?
Why silicon is used in scr?
For the same reason it is used in transistors and ICs: its a very good semiconductor. Note: equivalent devices have been made with germanium in the past, when most transistors were germanium. But they called them thyristors not GCRs.
Diodes and transistors are made of semiconductor material such as germanium and what?
Silicon
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 are PNP and NPN?
In most discrete bipolar junction transistors the substrate is the collector. In monolithic integrated circuits the bipolar junction transistors are electrically isolated from the substrate, either by reversed biased junctions or insulator (e.g. sapphire). Some older bipolar junction transistor types (usually made with germanium) the substrate is the base. In bipolar point contact transistors the substrate was the base.
How is germanium used inside computer chips?
It is not, silicon is. It is not possible to make ICs commercially using germanium (mostly because its oxide is crumbly and water soluble unlike silicon's oxide which is a stable and insoluble insulator, which means germanium ICs must be wired by hand under a microscope which is too costly for production). This means that germanium is limited to usage in discrete components (transistors & diodes) only. Some work is being done using silicon-germanium alloy for ICs, but it is not in the market yet.

What is a poem of germanium?
Germanium is a chemical element, not a poem. It is a metalloid commonly used in transistors and semiconductors due to its electrical properties.
Which technology are used in 2nd generation computer?
discrete transistors, usually made of germanium.
Is germanium explosive?
Germanium is not explosive. It is a chemical element with a low reactivity and has no explosive properties. It is commonly used in electronic devices and as a semiconductor in transistors.
Where is germanium used most?
Germanium is primarily used in the production of semiconductors for electronic devices such as transistors and diodes. It is also used in infrared optics, fiber optics, and as a catalyst in polymerization reactions.
Can germanium semi-conduct?
Yes, germanium can work as a semiconductor. It is used in electronic devices like diodes and transistors due to its semiconducting properties. Germanium was actually one of the first materials used in the development of semiconductor technology.
Why is germanium important?
Germanium is important because it is a semiconductor material used in electronics, such as transistors and diodes. It is also used in fiber-optic systems, infrared optics, and as a catalyst in certain chemical reactions. Additionally, germanium has potential applications in solar energy technology and as a health supplement.
