Semiconductors are materials that have electrical conductivity between that of a conductor (such as copper or aluminium) and an insulator (such as rubber or glass). They are widely used in communication systems for various applications including electronic devices, signal processing, and data transmission.
In communication systems, semiconductors are often used as the basic building blocks for electronic devices such as diodes, transistors, and integrated circuits. These devices are critical for controlling the flow of electrical signals in communication systems and enabling the processing and transmission of information.
One important application of semiconductors in communication is in the creation of photodiodes and photovoltaic cells, which are used in fibre optic networks to convert light signals into electrical signals and vice versa. Semiconductor lasers are also used as light sources in fiber optic communication systems.
Another important application of semiconductors in communication is in the creation of transistors, which are used as amplifiers and switches in electronic circuits. Transistors made from semiconductors can be used to control the flow of electrical signals, allowing for the creation of complex electronic systems such as microprocessors and memory devices.
Overall, semiconductors play a critical role in enabling communication systems to function and continue to be a key area of research and development in the field.
