Field effect may refer to: relative influence of electricity to the substrate within a given field.
*
Field effect (chemistry), an effect that a pole (either an unipole or dipole) has on a remote reaction centre (reaction rates, equilibrium). This effect operates through space not through bonds which distinguishes it from the
inductive effect
In Organic chemistry, the inductive effect in a molecule is a local change in the electron density due to electron-withdrawing or electron-donating groups elsewhere in the molecule, resulting in a permanent dipole in a bond.
It is present in a ...

Field effect (semiconductor)
In physics, the field effect refers to the modulation of the electrical conductivity of a material by the application of an external electric field.
In a metal, the electron density that responds to applied fields is so large that an external el ...
, the physical mechanism modulating the conductivity of a semiconductor using an applied voltage difference.
* Field effect also known as
field cancerization
Field cancerization or field effect (also termed field change, field change cancerization, field carcinogenesis, cancer field effect or premalignant field defect) is a biological process in which large areas of cells at a tissue surface or withi ...
, a field of molecular and cellular changes in normal appearing tissue, which predispose to the development of cancer.

Wien effect
The Wien effect is the experimentally observed increase in ionic mobility or conductivity of electrolytes at very high gradient of electrical potential. A theoretical explanation has been proposed by Lars Onsager.
A related phenomenon is known as ...
, in electrolytes, an increase in ionic mobility or conductivity of electrolytes at very high gradient of electrical potential.
