Semiconductors
A semiconductor is a material that falls between a metal and a dielectric in terms of electrical conductivity. This unique property allows semiconductors to conduct electricity under certain conditions, while blocking it in others. This behavior is due to the presence of impurities or dopants within the semiconductor lattice.
Semiconductors have a wide range of applications in various technologies, including:
Electronics: semiconductors are used in transistors, which are the basic building blocks of electronic devices such as computers, smartphones, and televisions.
Photovoltaics: semiconductors are used in solar cells, which convert light energy into electricity.
Sensors: semiconductors can be used as sensors to detect light, temperature, and other physical quantities.
Computing: semiconductors are used in logic gates and integrated circuits, which are the fundamental components of computers.
The study of semiconductors involves a deep understanding of their electronic structure, energy band theory, and how impurities and dopants affect their properties
