semikonduktori

Semikonduktori, or semiconductors, are materials with electrical conductivity between that of a conductor and an insulator. This unique property allows them to control the flow of electricity, making them fundamental to modern electronics. Common semiconductor materials include silicon and germanium, which are elements. Compound semiconductors, such as gallium arsenide, are also widely used.

The behavior of semiconductors is determined by their atomic structure and the presence of impurities, a process called doping. Doping introduces either excess electrons (n-type semiconductor) or electron holes (p-type semiconductor) into the material. When n-type and p-type materials are brought together, they form a p-n junction, which is the basis of many electronic components like diodes and transistors.

Diodes allow current to flow in one direction only, while transistors can amplify or switch electronic signals. These components are the building blocks of integrated circuits, also known as microchips or chips, which are found in virtually all electronic devices, from smartphones and computers to cars and medical equipment. The development and understanding of semiconductors have revolutionized technology, leading to miniaturization, increased processing power, and the creation of countless new applications. Their continued research and development are crucial for future technological advancements.
