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.

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.
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 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.

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.
Why is germanium important?
Germanium has many important uses that relate to science, medicine or even every day life. It is one of the largest used conductors used in transistors.
Diodes and transistors are made of semiconductor material such as germanium and what?
Silicon
Please Suggest equivalent transistor for AC 128.but it should not germanium transistor?
There are none. Germanium transistors are never equivalent to silicon.
How many transistors on an integrated circuit?
ICs have been built with as few as two to as many as hundreds of billions of transistors. I believe the first germanium prototype IC built by Kilby may have had only one transistor (it was an integrated circuit not for having many transistors, but because it integrated both resistors and transistors into a single germanium crystal).
