Puolijohteiset
Puolijohteiset are materials that have electrical conductivity between that of a conductor and an insulator. This means their conductivity can be manipulated by external factors such as heat, light, or the application of an electric field. Commonly, these materials are crystalline solids. The unique electrical properties of puolijohteiset arise from their atomic structure, specifically the way electrons are bound within the material. In conductors, electrons are loosely bound and can move freely, while in insulators, electrons are tightly bound and cannot move easily. Puolijohteiset fall in between, with some electrons able to move under certain conditions.
The most well-known puolijohteiset are elements from Group 14 of the periodic table, such as silicon and
