Abstract

1,034,824. Semi-conductor devices. AGENCY OF INDUSTRIAL SCIENCE & TECHNOLOGY, MINISTRY OF INTERNATIONAL TRADE & INDUSTRY. April 30, 1963 [April 30, 1962], No. 16874/63. Heading H1K. Electrical oscillations are generated by a semi-conductor device having a region in which its cross-sectional area changes abruptly, a unidrectional voltage being applied between the ends of the device and having means for injecting minority carriers into the device. As shown, Fig. 1A, a germanium crystal has a waist formed by machining or etching, an ohmic contact 2 and a minority carrier injection contact 2<SP>1</SP> such as a PN junction. When placed in series with a suitable voltage supply the device generates oscillations. Both end contacts may be ohmic and the carrier injection achieved by projecting light on to the device. The device may also have the configuration shown in Fig. 1B, and may have a rectangular, or circular cross-section. Two or more narrowed portions can also be provided. The oscillation can be modulated using a third terminal applied to the device, by modulating the light beam if this form of carrier injection is used, or by applying a magnetic field to the device. When the device is made of germanium a pulsed voltage is used to reduce heating. Continuous oscillation may be produced by using a constant voltage and cooling the device, mounting it under pressure, or using a gallium-arsenic alloy or cadmium sulphide crystal.
