Capacity for performing work or to cause heat flow. Like work
itself, it is measured in Joules.
Enthalpy (H)
A property of a system equal to E + PV, where E is the internal
energy of the system, P is the pressure of the system, and V is
the volume of the system. At constant pressure the change in
enthalpy equals the energy flow as heat.
Enzyme
A large molecule, usually a protein, that catalyzes biological
reactions.
Enzyme immunoassay/EIA
In an enzyme immunoassay (EIA), an enzyme-labeled antibody or
antigen is used for the detection and quantification of the
antigen-antibody reaction. In an electrochemical EIA, the
enzyme-catalyzed reaction is monitored electrochemically
(amperometric, potentiometric, voltametric or conductometric). In
EIA, the antibody-antigen reaction furnishes the needed
specificity. The enzyme label provides the sensitivity via
chemical amplification.
Epitaxial or epi
A single-crystal semiconductor layer grown upon a single-crystal
substrate having the same crystallographic characteristics as the
substrate material.
Characterizes doped, rather than pure, semiconductor.
Fab
For "fabrication", a term referring to the making of semiconductor
devices such as microprocessors.
Face-centered cubic
A crystal structure found in common elemental metals also
FCC. Within the cubic unit cell, atoms are located at all corner
and face-centered positions.
