Subject field(s)

  • Electronic Devices
DEF

A solid-state photosensitive electron device in which use is made of the variation of the current-voltage characteristic as a function of incident radiation.

OBS

Mention of the qualifier "solid-state" in this definition implies that phototubes are excluded from it. The Modern Dictionary of Electronic (Rudolf F. Graf, 5th ed. 1977) states that "the term should not be used for a phototube, which is a vacuum tube and not a cell". However, these terms are, in fact, often used in a more general sense to designate all types of light-sensitive electronic devices. This record deals with the terms in their more restricted sense.
