"0 and 2D semiconductor artificial junction... increased processing speed... joining quantum dots in a core-shell structure with zinc sulfide on surface of cadmium selenide and molybdenum sulfide semiconductor enabling storage and manipulation of electronic states within quantum dots measuring <=10 nm... ienables more states than 0 and 1... zinc sulfide shell prevents charge leakage between neighboring quantum dots, allowing each to function as memory... quantum dot structure perfectly mimics floating gate memory....
