Field effect

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, equiblirium). This effect operates through space not through bonds which distinguishes it from the inductive effect.
• Field effect (semiconductor), the physical mechanism modulating the conductivity of a semiconductor using an applied voltage difference.
• Field effect (medicine): Field effects within medicine follow textbook physiology and rigid rules. The Immersed Boundary Method governs the macroscopic scale of the interface between living blood and tissue. Individual fields of influence are numerous.
  1. neoplasm (also referred to as "field defect", "field cancerization", and "field carcinogenesis"), a field of molecular and cellular changes in normal appearing tissue, which predispose to the development of cancer.
  2. ischemia Resource variability within Substrate by gradual or sudden degradation of either Blood or Electricity sources. Encyclopedic definitions of gating, pooling and draining Hydraulics extends the utility of understanding the myocardium as the underlying substrate.
• Wien effect, in electrolytes, an increase in ionic mobility or conductivity of electrolytes at very high gradient of electrical potential.
