A semiconductor is a material between a conductor and an insulator. In layman's terms, it can either conduct current or prevent the flow of current. Its conductivity is lower than that of a conductor; It has a higher electrical conductivity than an insulator.

Semiconductor materials have special electrical properties and can be used to manufacture various electronic devices, such as integrated circuits, light-emitting diodes, solar cells, and so on. Because of their strong controllability, small size and low power consumption, semiconductor devices have been widely used in modern electronic technology.

Common semiconductor materials include silicon, germanium, gallium arsenide and so on. Their electrical conductivity can be regulated by means of doping (adding dopants) and PN junctions (structures between positive and negative charges), enabling the manufacture and application of different electronic devices.
A type of substance that conducts electricity worse than a conductor but better than an insulator is a semiconductor! Such as: germanium, silicon, is a semiconductor, semiconductor conductivity and temperature, pressure and other external factors related.
As the name suggests, the resistance value of a semiconductor is between a conductor and an insulator, of course, this range is very wide. The resistance value of the semiconductor also changes when the external conditions change, and it is by using this characteristic that the triode was invented and developed to the present chip.
semiconductor refers to a material whose electrical conductivity at room temperature is between that of a conductor and an insulator.
Semiconductors are used in integrated circuits, consumer electronics, communication systems, photovoltaic power generation, lighting, high-power power conversion and other fields, such as diodes are made of semiconductors.
A semiconductor is a material whose electrical conductivity at room temperature is between that of a conductor and an insulator. In other words, a material that can or can not conduct electricity. It is widely used in consumer electronics, communication systems, medical instruments and other fields. The core units in most electronic products, such as computers, mobile phones or digital recorders, are closely related to semiconductors.
Those that can be energized are called conductors, those that cannot be energized are called insulators, and there is something in between that can be energized and semi-energized, energized under certain conditions, otherwise they cannot be energized, which is called semiconductors, popular enough.
