Single atom metallic wires of arbitrary length are of immense technological and scientific interest. We present atomic-resolution scanning tunneling microscope data of a silicon-only template, which modeling predicts to enable the self-organized growth of isolated micrometer long surface and subsurface single-atom chains. It consists of a one-dimensional, defect-free Si reconstruction four dimers wide—the Haiku core—formed by hydrogenation of self-assembled Bi-nanolines on Si(001) terraces, independent of any step edges. We discuss the potential of this Si-in-Si template as an appealing alternative to vicinal surfaces for nanoscale patterning.

    Dysprosium disilicide can form nanowires and three dimensional (3D) islands on the Si(001) surface. The nanowire density and width are metal coverage dependent. Various superstructures are observed on the nanowires. The Si substrate is also reconstructed in either 2×4 or 2×7...

    We investigated the structure and electronic properties of unidirectional Pt2Si nanowires (NWs) grown on a Si(100)-2° off surface. We found that Pt2Si NWs were formed along the step edges of the Si(100)-2° off surface with c(4×6) reconstructions that occurred on the terraces of Si(100)...

    We have measured the electric properties of nanosized Schottky contacts formed between ErSi2 nanowires (NWs) and a Si(001) substrate. Current vs voltage (I-V) measurement was performed by touching a scanning tunneling microscope tip to the NWs. The current density (J) through the ErSi2/Si(001)...

    We prepared atomically flat Si(110), (111), and (001) surfaces using identical preparation conditions for a low-pH (pH < 1) HF treatment and a subsequent low-temperature (∼800 °C) anneal in H2. Atomic-resolution scanning tunneling microscopy (STM) revealed that the treated Si(110)...

    We investigate how and to what extent the one-dimensional (1D) subband separation of V-groove GaAs/AlGaAs quantum wires (QWRs) can be tuned in a controlled way without compromising the wire uniformity and interface quality. Our results demonstrate that high quality V-groove QWRs with subbands...

    Traveling reaction fronts in the oxidation of hydrogen on a Pt(111) surface were investigated by means of scanning tunneling microscopy (STM). The fronts were observed during dosing of the oxygen covered surface with hydrogen at temperatures below 170 K. The fronts represented 10 to 100 nm wide...

    Hydrogen incorporation in n-type Si-doped GaAs layers results in the neutralization of the active dopants and a change of the conductivity along the growth direction. To characterize the active dopant concentration of doped GaAs layers containing hydrogen, we have used secondary ion mass...
