Abstract:
A method of fabricating a crossed-wire device comprising a pair of crossed wires which form a junction where one wire crosses another and at least one connector species connecting said pair of crossed wires in said junction, said junction having a functional dimension in nanometers, said method comprising (a) forming said first wire, (b) depositing said at least one connector species over at least a portion of said first wire, and (c) forming said second wire over said first wire so as to form said junction, wherein said at least one connector species comprises a bistable molecule having a general formula given by where the letters in Formula (I) mean any of the following:A=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; B=CH; N; C-alkyl; C-halogen; ; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; D=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; E=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; F=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; G=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; J=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; K=CH; N; C-alkyl; C-halogen; Câ€”OH; Câ€”OR(ether); Câ€”SR(thioether); C-amide; C-ester or thioester; M=CH2; CF2; CCl2; CHOCH3; CHOH; CHF; CO; CH&boxH;CH; CH2â€”CH2; S; O; NH; NR; NCOR; or NCOAr; Q=CH; nitrogen; phosphorus; or boron; Y=O or S; and Z=R (H; alkyl); NHR; OR; SR; CHRâ€”NHR; CHRâ€”OR; CHRâ€”SR; CHRâ€”X (halogen); NRâ€”NHR; NRâ€”OR; or NRâ€”SR.
