ABSTRACT
We demonstrate x-ray diffraction measurements of internal strain in Si nanowires that were fabricated using a self-limiting oxidation process. Rod-shaped scattering around the 111 Bragg point due to interference effects from the Si nanowires were observed, which are robust reflections for incoherent displacement of the wires. From the shifts of the scattering in reciprocal space, the strain was estimated to be 1.0–1.5×10-3 for the sample oxidized at 800 °C for 300 min.

    We have fabricated Si nanowires (NWs) by breaking Si-Si tip-sample junctions and studied their conductance for both p-n and p-p-type junctions at room temperature. Upon breaking the junction by retracting the Si tip from the Si clean surface, the conductance decreases by orders of magnitude from...
