    Abstract: A logic device comprises a Gunn effect element having a capacitive element connected across its electrodes. The Gunn effect element is normally biased below the threshold value, and an input pulse is applied to raise the internal field of the Gunn effect element above the threshold value. The resultant charging of the capacitive element causes the Gunn effect element to be maintained in a state of oscillation.

    Abstract: A device is described for generating the beam effect in a semiconductor suitable therefor by applying a source of light at a portion of the semiconductor material to lower the resistance thereof and effectively raise the field intensity elsewhere in the semiconductor. The field intensity is produced by applying a voltage source across the semiconductor with a level selected to produce an electric field intensity in the material that is less than that necessary to produce Gunn oscillations but which is sufficiently high to permit the light source to trigger the semiconductor into high field domain Gunn oscillations.

    Abstract: A inhibited NOT circuit is described utilizing the Gunn effect. The NOT circuit is formed by connecting several semiconductor regions of the bulk negative resistance effect type in series relationship with interconnecting regions having sufficient conductivity to naturally suppress the formation of high field domains therein. The sizes and shapes of the semiconductor regions are so selected that in response to a bias voltage applied to electric field biasing electrodes one of the regions supports continuous high field domain oscillations unless inhibited by the formation of a high field domain in another semiconductor region. Several NOT logic devices are shown and described such as the NOR, the NAND and the R junction.

    Abstract: A neuristor element is described which is formed of a pair of Gunn effect elements using bulk negative resistance effect materials capable of forming high electric field layers in the elements upon the application of electric field intensities of preselected values within the materials. The elements are so coupled to one another that the initiation of a high electric field layer in one of them acts to inhibit the formation of such layer in the other element by effectively lowering the electric field intensity in the other element well below the threshold level necessary to form such high electric field layers. Several embodiments are described with one using capacitive coupling and another resistive or direct coupling.
