->
dark current
The current that flows in a photodetector when there is no optical radiation incident on the detector and operating voltages are applied.
EBIC
electron-beam-induced current
electric lamp
Any lamp whose emission of radiant energy is dependent upon the passage of an electrical current through the emissive medium.
electric-discharge lamp
A lamp that uses the transmission of an electric current through a gas or vapor to produce illumination. Neon, mercury and argon lamps are examples of electric-discharge lamps.
electroforming process
An electrochemical process of metal fabrication using an electrolyte, an anode to supply the metal, and a control of the electrical current and of the deposit of metal on the matrix of a reflector.
electrolysis
Conduction of an electric current through a chemical compound in its natural state, solution or as a molten, to decompose the compound.
electrolytic shutter
A high-speed shutter, similar to a Kerr cell, that uses the birefringence produced in a liquid during the passage of an electric current through it to change the liquid's optical transmission...
electron multiplication charge-coupled device camera
An EMCCD (electron-multiplying charge-coupled device) camera is a type of scientific camera specifically designed for low-light imaging applications that require high sensitivity and fast readout...
electron-gun system
An electron-gun system is an assembly used to generate and control a focused beam of electrons. Electron guns find applications in various fields, including cathode ray tubes (CRTs), electron...
electronics
That branch of science involved in the study and utilization of the motion, emissions and behaviors of currents of electrical energy flowing through gases, vacuums, semiconductors and conductors, not...
electrosensitive recording
A technique that uses the passage of an electrical current through a recording medium to produce a permanent image on that medium.
explosion spectrum
The light spectrum formed by an explosive reaction or by the electrical explosion of a metallic wire by a strong current.
