/ˈdaɪ.əʊd/, /ˈdaɪ.oʊd/
OriginFrom di- (“two”) + -ode. Learned formation, coined by William Henry Eccles in 1919, after Ancient Greek δίοδος (díodos, “passage through”), which however is formed not with δι- (di-, “two”) but with δια- (dia-, “through”).
- An electronic device that allows current to flow in one direction only; used chiefly as a rectifier.
“I propose to give the name diode to a tube with two electrodes.”
“If a crystal or a diode is used, the amplifier-voltmeter combination may be used with an amplitude-modulated source; or with a c-w source, the detector may be connected to a microammeter or galvanomet”
“In this circuit when the diode is forward biased, the voltage across the diode remains fairly close to the diode's barrier potential.”
