Abstract
An array of bistable devices includes a thin cadmium sulfide platelet having a first portion thereof that is substantially pure and the remaining portion thereof is implanted with atoms that can bind excitons. Such remaining portion can be implanted with ions from a lithium source. Apparatus for providing such an array can include a source of lithium ions and masking means for selectively permitting and for selectively inhibiting passage of ions from the source to pass therethrough and to implant in a pattern onto the platelet. The apparatus operates at temperatures in the neighborhood of liquid helium. A method for producing such an array includes providing a thin, substantially pure, platelet of cadmium sulfide, selectively masking the platelet with a pattern to selectively permit and to selectively inhibit passage of ions onto the platelet, and providing a source of ions. The source of ions, in accordance with certain features, can be lithium ions.
