  • Patent number: 9249354
    Abstract: Networks of semiconductor structures with fused insulator coatings and methods of fabricating networks of semiconductor structures with fused insulator coatings are described. In an example, a method of fabricating a semiconductor structure involves forming a mixture including a plurality of discrete semiconductor nanocrystals. Each of the plurality of discrete semiconductor nanocrystals is discretely coated by an insulator shell. The method also involves adding a base to the mixture to fuse the insulator shells of each of the plurality of discrete nanocrystals, providing an insulator network. Each of the plurality of discrete semiconductor nanocrystals is spaced apart from one another by the insulator network. The base one such as, but not limited to, LiOH, RbOH, CsOH, MgOH, Ca(OH)2, Sr(OH)2, Ba(OH)2, (Me)4NOH, (Et)4NOH, or (Bu)4NOH.
