Critical Absorption Energy - Measurement - Methods Based On Thermionic Emission - Work Function of Hot Electron Emitter
... In order to move from the hot emitter to the vacuum, the electrons must overcome an energy barrier determined simply by the thermionic work function of the emitter ... If an electric field is applied into the surface of the emitter, then the escaping electrons will all be accelerated away from the emitter and absorbed into whichever material is applying the electric ... law the emitted current density (per unit area of emitter), Je (A/m2), is related to the absolute temperature Te of the emitter by the equation where k is ...
Low-voltage Positive Emitter-coupled Logic
... In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family ... ECL uses an overdriven BJT differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and its slow turn-off behavior ...
