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
Is doping is used to increase the conductivity of intrinsic semi conductor material?
Doping a semiconductor provides additional charge carriers to the material. The dopant atoms are easily ionized, and this provides the semiconductor with either free electrons in the conduction band or electron vacancies (or holes) in the valence band, both of which allow the semiconductor to conduct electricity.
What is a semiconductor diode and their application?
It can be either a junction or point contact diode built with semiconductor material. there are many types depending on intended usage.junction diode is produced as described in its name by forming a junction in the semiconductor by using opposite types of dopant impurities.point contact diode is produced as described in its name by taking a semiconductor base and pressing a sharp metal point on its surface.A few of the types of semiconductor diodes are: small signal, power rectifier, zener, tunnel, gunn, etc.
Can you use semiconductor as a capacitor?
Transistor either increases or decreases current.. Capacitor stores energy
What is genetic material package in?
An organism's genetic material is packaged in its chromosomes. The genetic material can be in the form of either DNA or RNA.
Is silicon a extrinsic or intrinsic semiconductor?
silicon is intrinsic semiconductor until we add some impurities in it. the impurities are either of group 3 called acceptors which make p type or of group 5 called donors which make n type semiconductor.

Is metal a semiconductor or insulator?
Most metals are conductors. A semiconductor is a non-metal material like silicon or germanium which is'doped' with another substance to give the material either a surplus of outer-shell electrons, or a deficiency of them.
How can semiconductor material be made to become either a conductor or an insulator?
Semiconductor material can be made to become a conductor by doping it with impurities that introduce extra charge carriers. This increases the material's conductivity. On the other hand, to turn semiconductor material into an insulator, it can be cooled to very low temperatures to reduce the thermal energy of the charge carriers, effectively halting conductivity.
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.
What is the net charge on intrinsic N type material?
first of all un-doped semi-conductor is said to be intrinsic semi-conductor so, there is no discussion of either N-type or P-type
What is the process of adding impurities to a semi conductor?
The process of adding impurities to a semiconductor is called doping. It involves intentionally introducing specific atoms of different elements into the semiconductor crystal lattice to alter its electrical properties. This process can either create an excess of electrons (n-type doping) or holes (p-type doping) in the semiconductor material.
Is germanium n type semiconductor?
Yes, germanium can be doped to become an n-type semiconductor by introducing donor impurities such as phosphorus or arsenic. This process increases the number of free electrons in the material, giving it an excess of negative charge carriers.
What is a semiconductor diode and their application?
It can be either a junction or point contact diode built with semiconductor material. there are many types depending on intended usage.junction diode is produced as described in its name by forming a junction in the semiconductor by using opposite types of dopant impurities.point contact diode is produced as described in its name by taking a semiconductor base and pressing a sharp metal point on its surface.A few of the types of semiconductor diodes are: small signal, power rectifier, zener, tunnel, gunn, etc.

Why silicon is the more semiconductor than germanium?
Silicon is a more popular semiconductor than germanium due to factors such as its wider band gap, higher thermal stability, and better abundance in nature. Silicon also has better manufacturing processes and can operate at higher temperatures, making it more suitable for a wide range of electronic applications.
