Is lead a metalliod?
Though it shares the same group as carbon, silicon, and germanium, lead is definitely metallic. It is malleable, conducts heat and electricity well, is lustrous (though it oxidizes and dulls quickly,) and reacts with nonmetals easily to form compounds similar to those formed by other metals. The metalloids (or semi-metals) are: boron, silicon, germanium, arsenic, antimony, tellurium, and polonium. Their properties are essentially between those of the nonmetals and the metals, and they are the main ingredients in semiconducting materials. Aluminum falls in the region of the period table that makes up the metalloids, the stairstep pattern that starts with polonium and tellurium and climbs up to boron, but it is always considered a metal, as it has all of the properties that one typically associates with metals. Carbon, phosphorus, selenium, tin, and bismuth can show some of the characteristics of semimetals, depending on how the atoms are bonded together, or the allotrope in which they are found (graphite vs diamond for carbon, for instance.) no, lead is a metal. metalliod is a cross between a metal and a non-metal.
What are arsenic doped wafers used for?
Arsenic doped silicon wafers are used as the starting point for computer chips, memory chips, transistors, diodes, LEDs and many other devices. Arsenic is an n-type dopant in silicon, causing it to have an abundance of electrons (n for "negative"). A junction or diode is formed when an n-type region is in contact with a p-type region. A p-type region is formed with Boron for example as the dopant. Here there is a dearth of electrons (or equivalently an abundance of holes or absences of electrons). The holes act like positive carrier (p-type). The entire computer chip consists of lots of n and p regions that form circuits, transistors, etc. The wafer starts out arsenic doped, and then the various other dopants and additives are implanted or diffused into the surface. Then silicon dioxide is grown on top of the wafer which is insulating. Metal is desposited on top of that to create the wires interconnecting the various transistors on a chip. The wafer is diced up into the chips that get put in a package that you see on your computer board. You end up with an entire computer chip that started as an arsenic wafer.
Why is Bengaluru called the Silicon Valley of India?
Bangalore has been the IT capital of India since the late 1980s. In many ways, the culture, climate and progressive nature of entrepreneurs of Bangalore are conducive to innovative business, much like the San Francisco Bay Area, specifically Santa Clara and San Jose. This region of California is known as Silcon Valley owing to the predominance of semiconductor manufacturers, which paved the way to the high-tech and IT dominance of the area. Bangalore has been likened to this region and is hence known as the Silicon Valley of India. I also suspect it has something to do with the geography - Bangalore is actually on a plateau, but is also somewhat nestled between some mountainous regions, lending veracity to the 'Valley' part of its moniker.
Why leakage current of germanium is more than silicon?
Because the space charge region or depletion region is small in germanium compared to silicon hence leakage current is more in germanium than silicon
The Maximum spectral response of the germanium and silicon is in the X-ray region?
The Maximum spectral response of the germanium and silicon is in the x-ray region
The Maximum spectral response of the germanium and silicon is in which region?
ultraviolet region
Maximum spectral response of the germanium and silicon?
Visible region
What is meant by 0.3 volts for germanium and 0.7 volts for silicon?
== When we make a semiconductor junction (a p-n junction), the electric fields force charges to shift creating what is called a depletion region. This depletion region forms a potential barrier across the junction. This potential barrier has a voltage associated with it, and that voltage is 0.3 volts (approximately) for germanium semiconductor material, and 0.7 volts (approximately) for silicon semiconductor. The terms we apply to this barrier potential are the built-in voltage (or potential), junction voltage (or potential), and contact potential. Use the link below to check facts and review some other closely related material.
What is significance of depletion region?
Depletion region is the region where current carriers such as electrons and holes are absent.
What Depletion region will form?
Depletion region forms over poles. It is due to cool weather there.
What will happen to the depletion region when the P-N junction is supplied by forward bias?
depletion region will decrease.
At room temperature ther are 4.41010 intrinsic carriers showing that there are 4.41010 silicon ions but in the formation of depletion region you are saying donor and acceptor ion only why?

Where was germanium found?
Germanium was found in Germania. Latin for German Region in Germany
What happens in the depletion region in reverse bias?
in forward biasing depletion region width decreases and in reverse biasing it increases .
