Lake Worth, Florida Phone 582-3501 By DELOS SMITH I PI Science Editor NEW YORK (UPI)-A long-gathering revolution in electronics is now promising television receivers, ballistic missiles Immune to defensive antimissiles, and Is shut off entirely, it remains in whatever state it was in, conducting or blocking. Both are tiny, thin film upon which the disordered elemental chemical compounds have been selectively evaporated. A technology for exploiting the possible "phenomena" has great potential. basis, he has two devices. Both switch from blocking a current to conducting it in I.tO-trillionth of a second when the voltage of the current exceeds a pre-set threshold. When the voltage falls below the threshold it resumes blocking. One of the two has built-in "memorv." When the current crackerbox-size computer suitable for the home. All this and more It would do by replacing transistors and other components of electronic circuits with semi-conductors of electrical currents which are much smaller in size, cheaper and easier to make, and enormously faster and more versatile In operation. The revolution reached maturity in theoretical science Monday with publication of a paper entitled "Reversible Electrical Switching Phenomena in Disordered Structures" In a technical organ of the American Physical Society, "Physical Review Letters." From this maturity a complete technolgy must now be built which was true 21 years ago when the transistor itself reached theoretical maturity. ARE COMING!

The paper was theoretical proof that impure (or disordered) solid states of matter can be made to perform all the electronic wonders that pure (or ordered) solid states have been made to perform, and more, too. The author was Stanford R. Ovshinsky, electronics engineer and physicist of Troy, Mich. For years he was a lonely researcher into the possibilities of disordered solid states. Physicists knew that in some instances they could beelectro-nically manipulated but there seemed no practical way' of doing it. In 1966 Ovshinsky took out patents on devices which explored them. He then organized his own developmental corporation, Energy Conservion Devices, Inc. All semiconductors are so-called because they both block and permit the flow of electrical currents, depending on their design. Experimentally Ovshinsky developed disordered solid states with chemical forms of the elements, teillirium and selenium. Their electrically conducting atomics are weakly bound and subject to being either broken or united by controllable environmental circumstances such as the strength ofan electrical field.
