field effect
Noun
Meaning
field effect (plural field effects)
The use of an electric field to control the conductivity of a channel in a semiconductor, as in FET.
Alternative names
field-effect
Examples
A field-effect transistor ( FET ) is any semiconductor material that utilizes electric field to control the shape of a channel of one type of charge carrier, thereby changing its conductivity.
An insulated-gate field-effect transistor or IGFET is a related term almost synonymous with MOSFET.
Modern VLSI processors instead use matrices of field-effect transistors to build the ROM and/or PLA structures used to control the processor as well as its internal sequencer in a microcoded implementation.
Having unearthed Lilienfeld’s patents that went into obscurity years earlier, lawyers at Bell Labs advised against Shockley's proposal because the idea of a field-effect transistor that used an electric field as a "grid" was not new.
Field-effect phototransistors, also known as photoFETs, are light-sensitive field-effect transistors.
In 1926 Julius Edgar Lilienfeld patented a device resembling a modern field-effect transistor, but it was not practical.
