Publikováno v: Ultramicroscopy. 245:113667

All-graphenic carbon morphologies grown on individual carbon nanotubes (CNTs) consisting of short-fiber segments bearing sharp micro-/nano-cones at both ends were mounted as new probes for scanning probe microscopies (SPM). Three mounting procedures

High magnetic field spin-valley-split Shubnikov–de Haas oscillations in a WSe2 monolayer

Autor: Michel Goiran, M. Pierre, Bénédicte Warot-Fonrose, Banan Kerdi, Walter Escoffier, Robin Cours

Publikováno v: Physical Review B. 102

Here, the resistance of a WSe${}_{2}$ monolayer is measured under a strong, pulsed magnetic field. Non-$\frac{1}{B}$-periodic Shubnikov--de Haas oscillations are observed and attributed to a large spin-valley splitting of the valence band. The author

TEM characterization of the deformation micromechanisms in the case of AD730TM disk superalloy has been performed in order to identify the relevant parameters controlling its creep behavior at 700 °C under 600 or 850 MPa. The creep behavior has been
