SEMICONDUCTOR PHYSICS Meaning and
Definition
-
Semiconductor physics refers to the branch of physics that focuses on the study of semiconductors, which are materials that have intermediate electrical conductivity between insulators (materials that do not conduct electricity) and conductors (materials that readily conduct electricity).
Semiconductors are crucial components in many electronic devices, such as transistors, integrated circuits, and solar cells. Understanding semiconductor physics is vital for the development and improvement of these devices, as it helps scientists and engineers comprehend the behavior of electrons and holes (absence of electrons) in these materials.
In semiconductor physics, key concepts include energy bands, Fermi level, carrier concentration, and electron mobility. Energy bands describe the distribution of energy levels in a material, and electrons occupy these bands based on their energy states. The Fermi level represents the highest energy level occupied by electrons at absolute zero temperature. Carrier concentration refers to the number of available electrons or holes in a material, while electron mobility describes the ability of electrons to move through the material when exposed to an electric field.
Semiconductor physics also explores phenomena such as doping, where specific impurities are intentionally added to alter the electrical properties of semiconductors, and the creation and movement of electron-hole pairs, such as in the process of electrical conduction or the generation of electrical current in solar cells.
Overall, semiconductor physics forms the foundation for the understanding, design, and improvement of semiconducting devices, which play a central role in modern electronics and technological advancements.

Etymology of SEMICONDUCTOR PHYSICS
The word "semiconductor" originates from the Latin words "semi" meaning "half" and "ductor" meaning "conductor". It was coined in the early 20th century to describe a material that has conductivity between a conductor and an insulator.
The term "semiconductor physics" combines "semiconductor" with "physics", which comes from the Latin word "physica", meaning "natural science". Physics refers to the scientific study of matter, energy, and the interactions between them. Hence, "semiconductor physics" specifically denotes the branch of physics that focuses on the behavior, properties, and phenomena related to semiconductors.
