Key Differences
Semiconductors are materials with electrical properties that are intermediate between conductors and insulators. They are crucial in the production of a wide array of electronic components. On the other hand, a transistor is a specific type of semiconductor device that can amplify or switch electronic signals and electrical power.
The functionality of semiconductors arises from their ability to alter their conductivity with the addition of impurities—a process known as doping. Whereas transistors utilize this property to control current flow within an electronic circuit, acting as gates or switches.
Semiconductors can be elements like silicon or germanium or compounds such as gallium arsenide. In contrast, transistors are made specifically from semiconductor materials and are structured with at least three terminals for connection to an external circuit.
In terms of usage, semiconductors serve as the foundational material for not only transistors but also diodes, solar cells, and integrated circuits. On the other hand, transistors are primarily used in amplification and switching applications, crucial in devices from radios to computers.
Technological development in semiconductors focuses on enhancing material properties to improve overall device efficiency and capability. Meanwhile, advancements in transistor technology often involve scaling down sizes and increasing the density of transistors on a chip to enhance computational power and energy efficiency.
