A semiconductor is a material with conductive and insulating (electrical) properties. A semiconductor can pass current in certain situations, but it does not always pass current. This semi-conductor property makes it a suitable tool for electrical use with a controlled behavior where it is needed. Semiconductor conductivity depends on several factors such as the current or voltage applied to the control electrode or the intensity of emitting infrared (IR), visible light, ultraviolet (UV) or X-rays. Therefore, we can say that a semiconductor is a substance that has a higher electrical conductivity than an insulator, and this value is lower than that of a conductor. Examples of semiconductors include diodes, transistors, and many photovoltaic cells.In general, a semiconductor has a dual characteristic, it is both an insulator and an electrical conductor. This semiconductor property depends on the impurities added to the semiconductor materials (a pure semiconductor is called a pure semiconductor). Impurities added to semiconductor materials to change the electrical characteristics are called impurity impurity and the process of adding impurity is called doping. An N-type semiconductor is a type that carries current from negatively charged electrons. This is very similar to the current in a wire. A P-type semiconductor is a type that carries current mostly where there is a lack of electrons, which is called a hole location. The hole has a positive charge. This charge is equivalent to the charge of the electron. These holes flow in the opposite direction of electrons.

A semiconductor can help control electrical current. The basic use of a semiconductor is to turn the flux or electricity on and off when needed. A semiconductor can act as a vacuum tube with a hundred times the volume. A simple integrated circuit (IC) like a microprocessor chip can act like a set of vacuum tubes. Several types of materials and elements are used to make semiconductors. The semiconductor should not be a strong conductor or a weak conductor of electricity. Its properties can be changed by adding or removing atoms/impurities. Semiconductor materials include: timoane, arsenic, boron, carbon, germanium, gallium arsenide, selenium, silicon, silicon carbide, sulfur, tellurium, oxides of most metals. Or  silicon, which is a material that is widely used as a semi-material.In general, a superconductor is an intermetallic alloy or combination of electrical conductivity without resistance below a certain temperature. Once set, the electric current will flow forever in the closed loop of the superconducting material.

Conclusion : 

In general,  diffusion in electronics means   molecular   diffusion . A semiconductor is a material with conductive and insulating (electrical) properties. A semiconductor can pass current in certain situations, but it does not always pass current.
