3. Semiconductor Semiconductors are the materials which have a conductivity between conductors (generally metals) and non-conductors or insulators(such as ceramics). Semiconductors can be compounds such as gallium arsenide or pure elements, such as germanium or silicon. There are 2 Types of Semiconductor Intrinsic Semiconductor Extrinsic Semiconductor

4. Intrinsic Semiconductor Intrinsic Semiconductor :- An intrinsic (pure) semiconductor, also called an undoped semiconductor or I-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore determined by the properties of the material itself instead of the amount of impurities. Extrinsic Semiconductor :- Extrinsic semiconductors are semiconductors that are doped with specific impurities. The impurity modifies the electrical properties of the semiconductor and makes it more suitable for electronic devices such as diodes and transistors.

6. Difference between Intrinsic and Extrinsic semiconductor Intrinsic Semiconductor Semiconductor in Pure form is known as Intrinsic Semiconductor. Due to its pure form, intrinsic semiconductors possess low conductivity. Examples :- Pure Silicone, Pure Germanium. At Room Temperature No. of Electron=No. of Holes Extrinsic Semiconductor Semiconductor, Which isn’t in Their Pure form or Impure form is known as Extrinsic Semiconductor. extrinsic semiconductors exhibit comparatively better conductivity than intrinsic semiconductor . Examples :- n-Type Semiconductor and p-Type Semiconductor. In n-Type, No. of Electron>No. of Holes In p-Type, No. of electron<No. of Holes

7. Superconductor A material that shows zero electrical resistance and magnetic field to penetrate through is known as a superconductor, which is because of its superconductivity.  So, superconductors can conduct electricity without any loss. Usually, a material will achieve its superconductivity at a very cold temperature. Superconductor and superconducting materials are metals, ceramics, organic materials, or heavily doped semiconductors that conduct electricity without resistance. Superconducting materials can transport electrons with no resistance, and hence release no heat, sound, or other energy forms.

8. Application of Superconductor Superconductors are widely used in magnetic resonance imaging(MRI) and nuclear magnetic resonance imaging(NMRI). They are also used as the high energy particle accelerator in laboratories and also in nuclear fusion reactors. Superconductors are also used in fast digital circuits, Cell phone base Stations, power railguns and coilguns and also in particle detectors. Superconducting electromagnets are widely used in maglev trains.
