Phonon-Limited Mobility in H/F-functionalized Nanotubes with 1D -chains
V. L. Katkov, V. A. Osipov
Electron mobility due to electron-phonon interaction is investigated for fully fluorinated/hydrogenated zig-zag carbon nanotubes containing one-dimensional alternating chains of ca…
Jump of tunneling magnetoresistance in magnetic nanocontacts with mismatched cross section
V. L. Katkov, V. A. Osipov
We have studied the influence of the transverse size of a magnetic tunnel nanojunction on the magnitude of the magnetoresistance. During modeling, the size of the right contact was…
Effect of fluorine patterns on electronic transport in fluorinated graphene
Ruslan D. Yamaletdinov, Vsevolod L. Katkov, Yaroslav A. Nikiforov +2
Within the framework of stochastic reactive molecular dynamics simulations we develop a statistical method for generating fluorinated graphene structures with desirable fluorine di…
Effect of edge vacancies on performance of planar graphene tunnel field-effect transistor
A. A. Glebov, V. L. Katkov, V. A. Osipov
The influence of edge vacancies on the working ability of the planar graphene tunnel field-effect transistor (TFET) is studied at various concentrations and distributions (normal,…
Anomalous Tunneling Systems in Amorphous Organic Materials
S. Sahling, M. Koláč, V. L. Katkov +1
We compare the heat release data of organic glasses with that of amorphous and glass like crystalline solids. Anomalous behavior was found in all these materials, which disagrees w…
Anomalous Isotopic Effect of Tunneling States in NbTi-H/D
S. Sahling, S. Abens, V. L. Katkov +1
The thermal conductivity, heat capacity and heat release of NbTi, NbTi-H and NbTi-D were measured at low temperatures. All three systems reveal low temperature anomalies typical fo…
Relaxation time spectrum of low-energy excitations in one- and two-dimensional materials with charge or spin density waves
S. Sahling, G. Remenyi, J. E. Lorenzo +3
The long-time thermal relaxation of (TMTTF)Br, SrCuO and SrCaCuO single crystals at temperatures below 1 K and magnetic field up t…
Effect of edge vacancies on localized states in semi-infinite zigzag graphene sheet
A. A. Glebov, V. L. Katkov, V. A. Osipov
The effect of vacancies on the robustness of zero-energy edge electronic states in zigzag-type graphene layer is studied at different concentrations and distributions of defects. A…
Planar graphene tunnel field-effect transistor
V. L. Katkov, V. A. Osipov
We propose a concept for a graphene tunnel field-effect transistor. The main idea is based on the use of two graphene electrodes with zigzag termination divided by a narrow gap und…
Energy distributions of field emitted electrons from carbon nanosheets: manifestation of the quantum size effect
V. L. Katkov, V. A. Osipov
We emphasize the importance of experiments with voltage dependent field emission energy distribution analysis in carbon nanosheets. Our analysis shows the crucial influence of the…
Effect of band structure on field emission of crystalline graphite
V. L. Katkov, V. A. Osipov
The field emission of crystalline AAA graphite is studied within a simple analytical approach with account of the exact dispersion relation near the Fermi level. The emission curre…
