1957 H. Statz & R. A. Pucel in Proc. IRE 45 317/1 New devices are considered in which electrons or holes are injected directly into space-charge regions of reverse-biased junctions avoiding the diffusion of carriers through field-free regions. The case considered is one in which the junction is biased at a voltage such that the injected carriers are multiplied by the avalanche process. A device of this type shall be called a spacistor.
1969 A. Marcus Electronics for Technicians viii. 160 There is not, as yet, general agreement upon a symbol for the spacistor transistor.
1988 Solid-State Electronics 31 p. xix We worked on the ‘Spacistor’ a three-terminal device in which point contacts injected current directly into the transistor's collector depletion region for high speed.
