Understanding size/dimensionality-dependent phenomena and processes relevant to chemical sensing and catalysis requires analytical methods with high surface sensitivity, which can exploit the structure and composition of nanomaterials at their natural length scales and working conditions. In the present study, we explored the potentials and complementary capabilities of several surface-sensitive microscopy approaches to shed light on the properties of individual SnO(2) nanowires and their networks. Our results demonstrate the unique opportunities provided by synchrotron-based photoelectron microscopies for surface-sensitive structural and chemical analysis, including in situ characterization of electron transport properties of a nanostructure wired as an active element in chemiresistor devices.

    • "Perhaps, the main peak (centered at about 487.1 eV) was ascribed to Sn 4+ , while the binding energies 486.1 and 487.7 eV might be attributed to Sn 2+ and Sn organic complexes [23] [24]. The Sn 3d 3/2 spectra exhibited two peaks at 494.50 and 495.87 eV, which were assigned to Sn 2+ and Sn 4+ . "

    ABSTRACT: Hierarchical Sn3O4 nanoflowers, assembled from single-crystalline Sn3O4 nanosheets, were synthesized by a facile one-step hydrothermal route without any template. The crystal structure and phase purity of the Sn3O4 were investigated by X-ray diffraction (XRD). Morphologies and structures were analyzed by field-emission electron scanning microscopy (FESEM), and transmission electron microscopy (TEM), which indicated that flower-like Sn3O4 had an average size of about 700 nm and the surface of two-dimensional was smooth. BET results revealed the high surface area of the products (34.5 m2/g). The gas-sensing properties of flower-like Sn3O4 toward ethanol were investigated. Significantly, the sensor exhibited low detection limit and good repeatability to ethanol at the optimal operating temperature of 225 °C.

    • "In this respect, X-ray photoelectron spectroscopy (XPS) has provided important contributions to semiconductor research, monitoring changes in the chemical state, band bending, and photoemission-induced surface charging [12] [18] [19] [21]. Synchrotron light XPS has become a true microscopy technique, used recently for characterization of nanotubes, nanobelts, and NWs [22] [23] [24]. This study of undoped GaAs NWs prior to, and after, exposure to oxygen ambient demonstrates that by means of scanning photoelectron microscopy (SPEM) [25] it is possible to examine the interplay between NW diameter and conductance, combining full control of the surface chemical state with contactless monitoring of the changes in the conductivity along the axis of the NWs.

    ABSTRACT: Contactless monitoring with photoelectron microspectroscopy of the surface potential along individual nano-structures, created by the X-ray nanoprobe, opens exciting possibilities to examine quantitatively size-and surface-chemistry-effects on the electrical transport of semiconductor nanowires (NWs). Implementing this novel approach—which combines surface chemical microanalysis with conductivity measurements—we explored the dependence of the electrical properties of undoped GaAs NWs on the NW width, temperature and surface chemistry. By following the evolution of the Ga 3d and As 3d core level spectra, we measured the position-dependent surface potential along the GaAs NWs as a function of NW diameter, decreasing from 120 to ~20 nm, and correlated the observed decrease of the conductivity with the monotonic reduction in the NW diameter from 120 to ~20 nm. Exposure of the GaAs NWs to oxygen ambient leads to a decrease in their conductivity by up to a factor of 10, attributed to the significant decrease in the carrier density associated with the formation of an oxide shell.

    ABSTRACT: We report on the growth, structural characterization, and conductivity studies of Si-doped InP nanowires grown by Au-assisted molecular beam epitaxy. It is shown that Si doping reduces the mean diffusion length of adatoms on the lateral nanowire surface and consequently reduces the nanowire growth rate and promotes lateral growth. A resistivity as low as 5.1±0.3×10−5 Ω⋅cm is measured for highly doped nanowires. Two dopant incorporation mechanisms are discussed: incorporation via catalyst particle and direct incorporation on the nanowire sidewalls. The first mechanism is shown to be less efficient than the second one, resulting in inhomogeneous radial dopant distribution.
