Synthesis and luminescence properties of (N-Doped) ZnO nanostructures from a dimethylformamide aqueous solution

B. Sieber, Hong Liu, G. Piret, J. Laureyns, P. Roussel, B. Gelloz, Sabine Szunerits, Rabah Boukherroub

The paper reports on the optical properties of ZnO nanostructures elaborated on a zinc foil substrate by a simple chemical approach. The doping type and density of the ZnO nanostructures were evaluated using electrochemical impedance spectroscopy. XRD diffraction patterns and Raman spectroscopy…

To grate a liquid into tiny droplets by its impact on a hydrophobic microgrid

P. Brunet, F. Lapierre, Farzam Zoueshtiagh, V. Thomy, A. Merlen

We report on experiments of drop impacting a hydrophobic micro-grid, of typical spacing a few tens of µm. Above a threshold in impact speed, liquid emerges to the other side, forming microdroplets of size about that of the grid holes. We propose a method to produce either a mono-disperse spray or a…

Phonon surface mapping of graphite : disentangling quasi-degenerate phonon dispersions

A. Gruneis, J. Serrano, A. Bosak, M. Lazzeri, S.L. Molodtsov, L. Wirtz, Claudio Attaccalite, M. Krisch, A. Rubio, Francesco Mauri, T. Pichler

The two-dimensional mapping of the phonon dispersions around the K point of graphite by inelastic x-ray scattering is provided. The present work resolves the longstanding issue related to the correct assignment of transverse and longitudinal phonon branches at K. We observe an almost degeneracy of…

Universality of bias- and temperature-induced dephasing in ballistic electronic interferometers

Y. Yamauchi, M. Hashisaka, S. Nakamura, K. Chida, S. Kasai, T. Ono, R. Leturcq, K. Ensslin, D.C. Driscoll, A.C. Gossard, K. Kobayashi

We performed a transport measurement in a ballistic Aharonov-Bohm ring and a Fabry-P´erottype interferometer. In both cases we found that the interference signal is reversed at a certain bias voltage and that the visibility decays exponentially as a function of temperature, being in a strong…

Electrochemical impedance spectroscopy of ZnO nanostructures

Hong Liu, G. Piret, B. Sieber, J. Laureyns, P. Roussel, Wei-Jiang Xu, Rabah Boukherroub, Sabine Szunerits

The paper reports on the use of electrochemical impedance spectroscopy to determine the doping character and carrier density of freshly prepared and annealed ZnO nanostructures. The ZnO nanostructures were obtained by chemical oxidation of metallic Zn in a 5% N,N-dimethylformamide (DMF) aqueous…

Arsenic-segregated rare earth silicide junctions : reduction of Schottky barrier and integration in metallic n-MOSFETs on SOI

G. Larrieu, Dmitri Yarekha, Emmanuel Dubois, N. Breil, Olivier Faynot

As an attempt to considerably reduce the equivalent contact resistivity of Schottky junctions, this letter studies the integration of rare-earth silicides, known to feature the lowest Schottky barriers (SBs) to electrons, coupled with a dopant segregation based on arsenic (As$^+$) implantation.…
