We study the effect of Fe impurities deposited on the surface of the topological insulator Bi(2)Se(3) by means of core-level and angle-resolved photoelectron spectroscopy. The topological surface… Expand
Interaction between single walled carbon nanotube and 1D crystal in CuX@SWCNT (X = Cl, Br, I) nanostructures
Abstract CuX@SWCNT (X = Cl, Br, I) nanostructures were prepared by capillary filling of 1.4–1.6 nm single-walled carbon nanotubes (SWCNT) with copper halides. The structure of CuX@SWCNT (X = Cl, Br,… Expand
Evolution of carbon film structure during its catalyst-free growth in the plasma of direct current glow discharge
Abstract Catalyst-free growth of nanocrystalline carbon films on silicon substrates under direct current glow discharge in a mixture of hydrogen and methane was studied by scanning and transmission… Expand
One-Dimensional Crystals inside Single-Walled Carbon Nanotubes: Growth, Structure and Electronic Properties
Single-walled carbon nanotubes (SWNTs) discovered in 1993 are currently among the most exciting and promising nanostructures (Bethune et al., 1993; Iijima & Ichihashi, 1993). They arouse huge… Expand
The chemistry of imperfections in N-graphene.
Many propositions have been already put forth for the practical use of N-graphene in various devices, such as batteries, sensors, ultracapacitors, and next generation electronics. However, the… Expand
Photoemission of Bi2Se3 with circularly polarized light: Probe of spin polarization or means for spin manipulation?
Topological insulators are characterized by Dirac-cone surface states with electron spins locked perpendicular to their linear momenta. Recent theoretical and experimental work implied that this… Expand
Structure and electronic properties of AgX (X = Cl, Br, I)-intercalated single-walled carbon nanotubes
Abstract One-dimensional silver halide crystals were grown within single-walled nanotube (SWCNT) channels from the melt using a “molten media method”. Atomic structures of the AgX@SWCNT hybrids were… Expand
Kinetic Isotope Effect in the Hydrogenation and Deuteration of Graphene
Time-dependent photoemission spectroscopy is employed to study the kinetics of the hydro-genation/deuteration reaction of graphene. Resulting in an unusual kinetic isotope effect, the graphene… Expand
Phase relations in pseudobinary systems of germanium, tin, and lead chalcogenides
Available experimental data for the GeTe-SnTe, GeTe-PbTe, SnTe-PbTe, PbS-PbSe, PbS-PbTe, and PbSe-PbTe systems are critically evaluated, and their T-x phase diagrams are calculated. The results… Expand
