Why are semiconductors thermistors?
Semiconductors are thermistors because their electrical resistance changes with temperature. As the temperature of a semiconductor material increases, the movement of charge carriers within the material also increases, leading to a decrease in resistance. This property makes semiconductors suitable for use as thermistors, as they can accurately measure and respond to changes in temperature. Additionally, semiconductors have a predictable and repeatable temperature-resistance relationship, making them reliable for temperature sensing and control applications. **
What are semiconductors in physics?
Semiconductors are materials that have electrical conductivity between that of a conductor and an insulator. They are a crucial component in the field of electronics, as they can be used to control the flow of electrical current. Semiconductors are often used in the production of diodes, transistors, and integrated circuits, and are essential for the functioning of modern electronic devices such as computers, smartphones, and solar cells. In physics, the behavior of semiconductors is studied in the context of solid-state physics and quantum mechanics. **

Semiconductors conduct heat better than insulators because they have a higher thermal conductivity due to the presence of free electrons and holes. These free charge carriers can transfer thermal energy more effectively through the material. Additionally, the crystalline structure of semiconductors allows for efficient heat conduction as the atoms are closely packed together, enabling better thermal transport. Overall, the combination of free charge carriers and crystalline structure in semiconductors leads to better heat conduction compared to insulators. **
How do undoped semiconductors conduct electrical current?
Undoped semiconductors conduct electrical current through the movement of charge carriers, which can be either electrons or holes. At absolute zero temperature, the semiconductor is an insulator and no current can flow. However, as the temperature increases, some electrons gain enough energy to break free from their atoms and become mobile charge carriers, allowing current to flow. Additionally, at room temperature, some electrons from the valence band can be excited to the conduction band, leaving behind holes which can also contribute to the conduction of current. **
