What is an intrinsic semiconductor and what is an extrinsic semiconductor?
intrinsic semiconductor is an un-doped semiconductor, in which there is no impurities added where as extrinsic semiconductor is a doped semiconductor, which has impurities in it. Doping is a process, involving adding dopant atoms to the intrinsic semiconductor, there by gives different electrical characteristics
What is semi conductor diode?
Semiconductor diodes are made from the same Silicon, and occasionally Germanium, material that transistors, integrated circuits, etc. are made from. Diodes used in early electronic devices were made from vacuum tubes. Somewhat later diodes were made from finned stacks of Selenium. Simple "Crystal Radios" use Galena (lead ore) crystals with a steel pin that is manipulated to find a spot that allows electrical current to flow in only one direction.
What is the most familiar semiconductor?
silicon and germanium
Diodes and transistors are made of semiconductor material such as germanium and what?
Silicon
Can IInd group elements be used with silicon to make P- type semiconductor?
germanium
What is extrinsic and intrinsic?
A semiconductor material with electrical properties essentially characteristic of ideal pure crystal. Essentially silicon or germanium crystal with no measurable impurities
Why does an extrinsic semiconductor behave like an intrinsic semiconductor at high temperature?
With the increase in temperature, the concentration of minority carriers starts increasing. Eventually, a temperature is reached called the critical temperature (85° C in case of germanium and 200° C in case of silicon) when the number of covalent bonds that are broken is very large and the number of holes is approximately equal to number of electrons. The extrinsic semiconductor now behaves essentially like an intrinsic semi-conductor.

Is germanium a conductor or an insulator?
neither, germanium is a semiconductor

Is gold a better conductor than germanium?
Yes. Pure gold is a much better conductor than pure germanium is.
What is doping in conductor?
The process of adding suitable impurities in the intrinsic semiconductor is called doping. The impurity added to the intrinsic semiconductor to increase its conductivity is called dopant. There are some methods of doping in case of a conductor.impurity atoms can be added to the intrinsic semiconductor in different ways discussed below:A very small quantity of impurity atoms is made by diffusing into the high purity molten material such as germanium when the crystal is grown out of melt.Impurity atoms can also be added into the intrinsic semiconductor by heating it in the environment having impurity atoms.Impurity atoms can also be added into the intrinsic semiconductor by bombarding it with the impurity atoms.
Is germanium a conductor of electricity?
Germanium is a semiconductor, meaning it can conduct electricity under certain conditions. It does not conduct electricity as well as metals like copper or silver, but it is commonly used in electronic devices and transistors.
What do you call a single element semiconductor material such as silicon and germanium?
Intrinsic semiconductivity
Is germanium a good conductor of electricity?
Germanium is a semiconductor, which means its conductivity falls between that of a conductor and an insulator. It is not as good a conductor as metals like copper, but it can conduct electricity under certain conditions.
Is germanium is a better conductor?
No, germanium is not a better conductor than metals such as copper or silver. Germanium is a semiconductor that has electrical conductivity between that of a conductor and an insulator. It is commonly used in electronic devices for its semiconducting properties.
What is ge germanium used for?
An Important Use Of Germanium Is That It's A Semi-Conductor (Semiconductor.) A Semi-Conductor Will Only Conduct Things, Such As Heat, So Well, And Only So Many Of Times You Try.
