单词 | molecular electronics |
释义 | molecular electronicsn. Electronics. 1. = microelectronics n. a. Now historical.The term originated with a project of the U.S. Air Force in 1959 which had the aim of developing electronic devices in which individual molecules do the switching (cf. sense 2), but which in practice resulted in the development of integrated circuits.

Times 3 Jan. 1 f/2 The chief executive officer..disclosed that Westinghouse was actively engaged in ‘molecular electronics’. 1960 Science 21 Oct. 1133/3 The subject of this article has been called ‘solid circuits’, ‘semiconductor networks’, and ‘integrated circuits’, as well as ‘molecular electronics’. 1963 Adv. Computers 4 141 ‘Integrated’ circuits fabricated using ‘molecular electronics’ techniques. 1965 Science 19 Mar. 1472/2 Westinghouse, a pioneer in molecular electronics, is supplying 3000 microcircuits for each airborne Univac 1830 computer. 1977 Science 18 Mar. 1155/3 The need for simplified field maintenance and the stringent power and weight constraints on airborne equipment motivated [U.S.] Air Force support of ‘molecular electronics’, an unfortunately named project that was nevertheless one of the key initiating events in the development of integrated circuits. 1982 E. Braun & S. Macdonald Revolution in Miniature (ed. 2) viii. 95 The [U.S.] Air Force supported another idea, what is called molecular electronics, from 1959. 1998 P. Ceruzzi Hist. Mod. Computing vi. 181 The press..called the use of ICs an ‘interim step’ needed to reduce the size and complexity of airborne electronics. The term ‘molecular electronics’ quietly vanished from subsequent reports. 2. A branch of electronics in which individual molecules perform the same function as microelectronic devices such as diodes.

National Acad. Sci. U.S.A. 83 5355 Molecular electronic devices and ‘molecular electronics’ are increasingly attracting attention. 1993 Wired Dec. 87/1 Even molecular electronics is just a way-station along the path to true molecular nanotechnology. 1995 Canad. Chem. News (Nexis) 47 32 This area also encompasses molecular switches and molecular wires necessary for the future applications of molecular electronics. 1999 N.Y. Times 1 Nov. c1/3 Other groups are preparing to announce that they have succeeded in creating other basic computing components at this ultramicroscopic scale, known as molecular electronics. 2000 Wired July 244/1 His newest molecules exhibit semiconductive properties that give them the ability to hold a charge or behave like switches or memory, meaning molecular electronics could replace the transistors, diodes, and conductors of conventional microelectronic circuitry. This is a new entry (OED Third Edition, September 2002; most recently modified version published online March 2022). < |
