Can you dope a semiconductor with holes instead of electrons?
Doping with Group III elements, which are missing the fourth valence electron, creates "broken bonds" (holes) in the silicon lattice that are free to move. The result is an electrically conductive p-type semiconductor.
Diffrentiate n-type and p-type?
When pentavalent impurity is added to pure semiconductor, it is known as N-Type semiconductor. In N-type semiconductor electrons are majority carriers where as holes are minority carriers. impurities such as Arsenic, antimony are added. When trivalent impurity is added to pure semiconductor, it is know as P-type semiconductor. In P-type semiconductor holes are majority carriers whereas electrons are minority carriers. Impurities such as indium, galium are added.
When silicon is doped with phosphorous what type of semiconductor results?
it would be a n-type semiconductor because phosphorus has more valence electrons than silicon does.
Why the semiconductor behave like a insulator as a zero?
O K is absolute zero. At absolute zero, the electrons of the semi conductors are trapped and are immovable from their electron shell as they are in a low energy state. This makes the pure semiconductor an insulator. One must heat the semiconductor to give the electrons enough energy to move to free them from their electron shell, and thus conduct.
Why CdS is always n type semiconductor?
CdS is considered as n-type semiconductor because of the deficiency of sulfur. This creates vacancies with a high electron affinity and causes CdS to acquire electrons easily.

What term is given to the process of rearranging electrons in a semiconductor by adding atoms of other elements?
Doping is the term used to describe the process of adding atoms of other elements to a semiconductor to alter its electrical properties by rearranging the electrons.

What is the number of free electrons and holes in a pure semiconductor at 0k?
There are no free electrons and holes in a pure semiconductor at 0k.

Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.
How many valance electrons does a semiconductor have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
