kenttävaikutteinen

Kenttävaikutteinen is a Finnish adjective meaning influenced by an external field, such as an electric, magnetic, or gravitational field. The term is used in physics, chemistry, and engineering to describe phenomena, devices, or processes where an applied field modifies a system’s properties or behavior.

In electronics and solid-state physics, kenttävaikutteinen refers to field-effect phenomena in which an electric field modulates charge carrier density and conductivity, as in field-effect transistors. In chemistry and molecular physics, electric or magnetic fields can influence reaction rates, selectivity, or the orientation of molecules, producing field-induced effects. In materials science, external fields can affect phase transitions, polarization, magnetization, or optical properties.

The mechanisms involved include shifting energy levels, reorienting dipoles, and redistributing charges. The concept is used to describe how external fields tune physical properties without changing composition, enabling control of devices and materials.

Etymology: kenttä means field, vaikuttava or vaikuttaminen relates to influence or effect. The term is often translated as field-induced or field-effect in English, depending on the context.
