ABSTRACT
A robust technique for fabrication of metal wires with controlled widths substantially below 10 nm is presented. By etching a cleaved molecular-beam epitaxy grown substrate, a mechanical template is produced with surface relief of atomic lateral definition. Using metal deposition and directional ion etching of such a substrate, electrically continuous wires are formed from AuPd alloy with diameters as small as 3 nm and lengths greater than 1 μm. This technique can be used with a variety of materials and makes metallic nanostructures on a previously inaccessible size scale. © 2000 American Institute of Physics.

    We have studied the effect of molecular beam epitaxy growth conditions on the surface morphology of strained InAs/GaAs(331)A films. Our results reveal that InAs nanowires aligned along the [110] direction are lbrmed under As-rich conditions, which is explained by the effect of anisotropic buffer...

    The shape and facets of GaAs nanowires grown by molecular beam epitaxy have been identified by the use of the diffuse scattering around the Bragg reflection from the parts of the nanowires having different crystal structures. The zinc blende parts of the nanowires are shown to have {111} facets...

    The formation and properties of radial heteroepitaxial ZnO/(Mg,Zn)O nanowires is reported in which the (Mg,Zn)O is cubic. Synthesis is achieved via a catalyst-driven molecular beam epitaxy technique. The nanowires were grown on Ag-coated Si substrates at growth temperatures ranging from Tg=300...

    Heteroepitaxial growth of InAs was investigated on sidewalls of InP nanowires (NWs) using metal-organic vapor phase epitaxy. InAs quantum wells (QWs) with smooth surface were formed on the InP NWs having perfect wurtzite phase structure. On the other hand, InAs quantum dots (QDs) were formed on...

    We studied the conditions for the Stranski-Krastanov mode of molecular beam epitaxial growth of InAs on a cleaved GaAs(110) surface. Temperature distributions on a subholder with cleaved facets were revealed using thermophotography. Combining these data with a theoretical model enabled a...

    HgTe nanowires have been grown by molecular beam epitaxy (MBE). They are nucleated at Au particles on Si or GaAs substrates and subsequently self-organize and grow laterally on the surface into 20-50 nm wide, 0.5-1 µm long twisted, but single-crystal, wires. Further growth gives longer,...

    HgTe-CdTe heterostructures have been grown by molecular beam epitaxy on (100) InSb substrates. Separate elemental Hg and Te beams were used for the HgTe growth at a substrate temperature of 160 °C. X-ray diffraction measurements indicate that thin epitaxiat layers are of high crystalline...
