Published on Nov 24, 2023
Semiconductors can be broadly categorized into two types: intrinsic and extrinsic. Intrinsic semiconductors are pure semiconducting materials such as silicon and germanium, while extrinsic semiconductors are doped with impurities to alter their electrical properties.
Intrinsic semiconductors are characterized by their ability to conduct electricity under certain conditions. Silicon and germanium are the most commonly used intrinsic semiconductors in the electronics industry. These materials have a crystalline structure and are capable of conducting electricity at room temperature.
Extrinsic semiconductors are created by introducing controlled amounts of impurities, known as dopants, into the crystal lattice of the semiconductor material. This process is called doping and is used to modify the electrical properties of the material. The two main types of extrinsic semiconductors are n-type and p-type, which exhibit different conductivity properties.
Semiconductors have a wide range of applications in various technological fields. Some of the key areas where semiconductors are used include:
