An extrinsic semiconductor is a material whose electrical properties have been modified by the deliberate addition of impurities, called dopants, to enhance its conductivity. This process creates either an excess of electrons (n-type) or holes (p-type), allowing for precise control over the semiconductor's electrical behavior, crucial for electronic devices like diodes and transistors.

Diodes are semiconductor devices that allow current to flow in one direction only, functioning as a one-way valve for electric current. They are essential components in converting alternating current (AC) to direct current (DC) and are used in various applications such as rectifiers, voltage regulators, and signal demodulators.

diodes

Transistors are semiconductor devices used to amplify or switch electronic signals and electrical power, forming the fundamental building blocks of modern electronic devices. They revolutionized technology by enabling the miniaturization and increased power of circuits, leading to the development of computers, smartphones, and other digital devices.
