IPC: H01J19/42
Filed: 1948-11-26
Abstract: 695,011. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. Nov. 25, 1949 [Nov. 26, 1948], No. 30706/48. Class 40 (iv). [Also in Groups XXXVI and XL (a)] An electric circuit element in an evacuated envelope comprises an indirectly heated oxidecoated cathode, and an electrode in contact with the cathode over a restricted area to provide a rectifying contact. A second electrode may also be provided so that the arrangement operates as a transistor. Fig. 2 shows a construction in which the indirectly heated cathode 3 is formed by a nickel sleeve coated with oxide material such as a barium, strontium and calcium carbonate mixture. A metal probe 12 of tungsten wire is arranged to contact the oxide layer, this contact having a non-linear resistance characteristic similar to that of a germanium crystal rectifier except that the reverse current is smaller than that of a normal crystal rectifier for relatively large reverse bias voltages. A normal anode 14 having an aperture for the wire 12 may also be provided together with a control grid, so that the arrangement then resembles a diode-triode valve. If the probe is heated the reverse current is increased and this is utilized in a modification which is described wherein an " emitter " and a " collector " electrode are provided in contact with the oxide layer, the arrangement then resembling a transistor. In Fig. 5, two ceramic tubes 19, 20 are placed flush with, or slightly below the surface of the metal cathode sleeve 17, and carry a pair of fine wires 22, 23 forming the emitter and collector electrodes respectively. The wires are then embedded in a surface oxide coating 24, and the assembly is mounted in a valve envelope similar to that shown in Fig. 2. The emitter electrode should be heated either by passing current, or as a result of being embedded in the oxide layer, to approximately 1000‹ K., and should be biased slightly positive relative to the cathode, the " collector " electrode being biased negatively. Variations in the potential of the emitter electrode control the collector current, so that the device may be used as an amplifier or an oscillator. To increase the output impedance of the device, the collector electrode may be in the form of a pointed probe of thin wire carburized at its tip. A normal anode may also be provided in the valve assembly. The Provisional Specification refers to the use of tapes for the electrodes, and also states that these may consist of bipolar series-wound around the cathode and may be the means for heating the cathode. The use of the heating current, and thermionic current as a means of adjusting the rectifier or amplifying characteristics is also referred to.
