Abstract:
1. A method of making a nanowire based device, comprising: depositing a plurality of nanowires on at least a first region of a surface of a substrate; and forming at least first and second electrical contacts on the first region of the surface of the substrate such that at least a first nanowire of the plurality of nanowires is positioned in contact with both the first and second electrical contacts, wherein the plurality of nanowires are made from a material selected from the group comprising Si, Ge, Sn, Se, Te, P, Si—C, Si—Ge, Si—Sn, Ge—Sn, SiC, AlN/AlP/AlAs/AlSb, GaN/GaP/GaAs/GaSb, InN/InP/InAs/InSb, AlN/AlP/AlAs/AlSb, GaN/GaP/GaAs/GaSb, InN/InP/InAs/InSb, ZnO/ZnS/ZnSe/ZnTe, CdS/CdSe/CdTe, HgS/HgSe/HgTe, BeS/BeSe/BeTe/MgS/MgSe, GeS, GeSe, GeTe, SnS, SnSe, SnTe, PbO, PbS, PbSe, PbTe, CuF, CuCl, CuBr, CuI, AgF, AgCl, AgBr, AgI, BeSiN2, CaCN2, ZnGeP2, CdSnAs2, ZnSnSb2, CuGeP3, CuSi2P3, (Cu, Ag)(Al, Ga, In, Tl, Fe)(S, Se, Te)2, Si3N4, Ge3N4, Al2O3, (Al, Ga, In)2(S, Se, Te)3, or Al2CO or alloys thereof, wherein the first and second electrical contacts are separated from each other on the first surface of the substrate by a distance that is less than 50% of an average length of the plurality of nanowires.
