ovonic, a. Electronics.|əʊˈvɒnɪk|
Also Ovonic.
[f. ov- (in the name of Stanford R. Ovshinsky (b. 1922), the U.S. physicist and industrialist who discovered the property) + -onic (in electronic).]
Pertaining to, involving, or utilizing the property of certain amorphous semiconductors of making a rapid, reversible transition from a non-conducting to a conducting state on the application of an electric field stronger than some minimum value.
1966Electronics 19 Sept. 191/2 This month, Ovshinsky..was able to let the cat out of the bag. His company..calls the device by its trade name, Ovonic. 1968S. R. Ovshinsky in Proc. Electronic Components Conf. (Washington) 313 The Ovonic Threshold Switch (OTS) and the Ovonic Memory Switch (OMS) are described. 1968Daily Tel. 12 Nov. 22/6 A company founded by Mr. Ovshinsky to develop glass semi-conductors is producing 150,000 ‘ovonic’ devices a day. These are in the form of glass film a twentieth of the thickness of a human hair. 1968Economist 30 Nov. 45/1 The big electronics research laboratories have been sceptical and even a bit cross that Mr Ovshinsky has put his name on to the ‘ovonic devices’ and the ‘Ovshinsky effect’. Bell Telephone Laboratories declared that one of its scientists presented the first paper describing glass semi-conductors six years ago. 1970S. R. Ovshinsky in McGraw-Hill Yearbk. Sci. & Technol. 359/1 Since ovonic switches have a number of unique characteristics, they are applicable to a wide range of uses. 1971R. G. Neale et al. in W. B. Riley Electronic Computer Memory Technol. vii. 192/2 Each cell in the memory consists of an Ovonic amorphous semiconductor device and an isolating diode in series on a silicon substrate. 1973IEEE Trans. Electron Devices XX. 190/1 A very high-speed electrically alterable read-only memory using Ovonic memory cells..has been designed and tested for use in the terminal multiplexor.
Hence oˈvonics n. pl. (const. as sing.) [-ic 2], the study and application of ovonic effects and devices.
1968Economist 30 Nov. 45/2 There are problems on the ovonics side too. The reliability of the glass semi-conductors is still suspect. 1969Sci. Jrnl. Aug. 78/3 Other fields of application for Ovonics lie in a.c. control where the bidirectionality of Ovonic switches will be of prime importance. |
