The device is called a diode because it has two terminals, and the name is also convenient because it allows the use of anode for the “positive end of the slice. Experimental results are presented for fundamental logic performances in a planner Gunn-effect device with two separated cathodes, which was fabricated on an epitaxial GaAs grown on a semi-insulating substrate. By selecting the polarity of input trigger pulses with respect to that of the biasing voltage, two functions, exclusive-OR (comparator) and inclusive-OR can be realised, as found by our Cited by: 1. A further logic circuit is a Gunn-effect memory device, as shown in Fig. 3. The comparator enables one to switch the ring between `on' and `off'. If a negative pulse is applied at I, a signal will travel continuously round the loop formed by the comparator and the Gunn-effect diode D.

Further logic Gunn-effect elements have been reported’4*5’ such as an ‘exclusive or’, which is the basic device for an adder. These new devices should enable the development of exten-sive logic circuitry by utilizing the already available Gunn-effect elements. A method of fabricating planar Gunn-effect devices with Schottky-barrier gates has been improved by using the self-alignment technique. Dual-gate devices fabricated by this method have fine geometries and exhibited sufficiently good performance.

Logic Devices III 1 Fundamentals of Logic Devices Requirements for Logic Devices In order to perform information processing in the real, physical world, the logical states must be mapped onto physical properties. This mapping may take place eh tn•o amplitude of physical properties, as e.g. the voltage levels in the CMOS cir-cuits, or.
