APPLICATION OF SEMICONDUC
TORS
THE PURPOSE OF THIS WORK IS TO GET ACQUAINTED WITH THE VARIOUS
APPLICATIONS OF SEMICONDUCTORS

2.

SEMICONDUCTORS
1. Semiconductors are materials that have the ability to conduct electric
current, but not as well as metals
2. The valence band of electrons is filled in semiconductors, but electrons are
absent in the band gap
3. They have many defects in the crystal lattice, which makes it possible to
add various elements in order to obtain the necessary properties
4. Representatives of semiconductors : Si, Ge, GaAs, SiC and many others

THE POSITIVE ASPECTS OF USING
SEMICONDUCTORS
1. Semiconductors have high electrical conductivity, which allows them to be used in
electronic devices
2. Semiconductors have a compact size and light weight, which makes them ideal for
use in microelectronics and other miniature devices.
3. Semiconductors can operate over wide temperature ranges, which makes them
reliable and stable in various operating conditions
4. They consume less energy and generate less heat compared to other types of
materials, which helps to reduce energy costs and increase the efficiency of
devices.

WHERE ARE SEMICONDUCTORS USED
1. Electronics: Semiconductors are used in the creation of electronic components
such as transistors, diodes, thyristors and integrated circuits
2. Solar panels: Semiconductor materials such as silicon are used to create solar
panels that convert sunlight into electrical energy. Solar energy is becoming an
increasingly popular and environmentally friendly source of energy
3. Optoelectronics: Semiconductor materials are also used in optical devices and
devices such as LEDs (LED indicators, LED screens), lasers and photodiodes
4. Medicine: Semiconductors are widely used in medical devices and technologies
such as electrocardiographs, ECG devices
