British Dictionary definitions for diode
/ (ˈdaɪəʊd) /
a semiconductor device containing one p-n junction, used in circuits for converting alternating current to direct current: More formal name: semiconductor diode
the earliest and simplest type of electronic valve having two electrodes, an anode and a cathode, between which a current can flow only in one direction. It was formerly widely used as a rectifier and detector but has now been replaced in most electrical circuits by the more efficient and reliable semiconductor diode

Scientific definitions for diode
[ dī′ōd′ ]
An electrical device with two active terminals, an anode and a cathode, through which current passes more easily in one direction (from anode to cathode) than in the reverse direction. Diodes have many uses, including conversion of AC power to DC power, and the decoding of audio-frequency signals from radio signals.
