What else can I help you with?
Is germanium ductile?
No, germanium is very brittle.
Was Germanium used 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.
Who developed the first transistor?
The first computer (a mechanical analog computer) is believed to have been invented circa 100BC by Archimedes.The first digital computer (a mechanical computer) was invented about 1837 by Charles Babbage.The first electronic digital computer was invented in 1937 by John Vincent Atanasoff.The first integrated circuit (a hybrid device) was invented between 1949 and 1951 independently by Werner Jacobi, Geoffrey W. A. Dummer, and several others; however the first working units had to be built with sockets for special miniaturized vacuum tubes, it was only late in the 1950s that transistors replaced the tubes in these devices.The first monolithic integrated circuit was invented in 1958 by Jack Kilby, this germanium device was not very practical to manufacture and never went beyond prototype development.The first practical monolithic integrated circuit was invented independently in 1959 by Robert Noyce, this silicon device was rapidly improved on.The first transistor (a germanium point contact transistor) was invented in 1947 by John Bardeen and Walter Brattain.The first junction transistor (a germanium grown junction transistor) was invented in 1948 by William Shockley.
What is a substitute for a germanium diode?
There is no exact substitute for a germanium diode, except another germanium diode. However if the only concern is to get a lower forward voltage drop than that of a silicon diode (0.7V), then a schottky barrier diode may be a suitable replacement as its forward voltage drop (<0.1V) is even lower than that of a germanium diode (0.2V).
The addition of arsenic to germanium makes the latter a an- a) Extrinsic semiconductor b) Metallic conductor c) Intrinsic semiconductor d) Mixed conductor?
The addition of arsenic to germanium makes it an extrinsic semiconductor (option a). This is because arsenic acts as a dopant, introducing free charge carriers (electrons) into the germanium, which enhances its electrical conductivity compared to intrinsic germanium.
When was microchips invented?
The microchip was invented by Robert Noyce and Jack Kilby. A microchip is built by layers of a semiconductor material of silicon or germanium
Who invented the first semiconductor diode what it is called as and from which metal it is made up of?
The first modern semiconductor diode was made with germanium. These diodes were invented in ww2 for RADAR. But before that semiconductor diodes were made with galena (lead sulfide), copper oxide, and selenium. I have no idea which was "first".
What does germanium do?
Germanium does no "do" anything.
Who is Germanium manufactured?
Germanium is not manufactured; its ore is mined then refined into germanium.
How many electrons does germanium have?
Germanium has 32 electrons.
What is a germanium's atomic number How many electrons does germanium have?
Germanium Atomic number is 32 and the number of electrons is 32
How many protons are in the element germanium?
Germanium has 32 protons.
How many protons does germanium have?
The element germanium has 32 protons.
Does germanium form any isotopes?
Yes, germanium does form isotopes. It has five stable isotopes: germanium-70, germanium-72, germanium-73, germanium-74, and germanium-76. Additionally, there are several unstable isotopes of germanium that have been produced in laboratories.
What compounds contain germanium?
Germanium can be found in compounds such as germanium dioxide (GeO2), germanium tetrahydride (GeH4), and germanium tetrachloride (GeCl4). These compounds are important in the electronics industry and for various chemical applications.
Is germanium ductile?
No, germanium is very brittle.
Is germanium a insulator of electricity?
Germanium is a semiconductor
