The use of γ-graphyne-1 nanotubes (GyNTs) in tunneling field effect transistors (TFETs) suppresses ambipolarity and enhances the subthreshold swing (\(\mathrm{SS}\)) TFETs, due to large energy band gap high electron effective mass GyNTs. In this research, analysis structural, electronic thermoelectric properties family under deformation potential (DP) approach reveals that electron–phonon mean ...

h6-benzne, h6-garphyne) was studied with MPW1PW91 quantum chemical computations. Quantumtheory of atoms in molecules (QTAIM) was applied to elucidate these complexes Cr-CO bonds. Theellipticity (e) and h values of the Cr-CO bonds were calculated. The amount of pp-dp back-donation ofCr-CO bonds were illustrated by calculation of the magnitude of the quadrupole polarization of c...

The study of higher-order and real topological states as well the material realization have become a research forefront condensed matter physics in recent years. Twisted bilayer graphene (tbG) is proved to topology. However, whether this conclusion can be extended other two-dimensional twisted carbon materials mechanism behind it lack explorations. In paper, we identify $\ensuremath{\alpha}$-gr...

s of the Posters Ngoc Do, Some graph models in nano-science and solid state Abstract: Graph model is proven in many cases to be much simpler to study than other approaches and yet preserves all essential ingredients of the dispersion relation. We study some spectral problems for periodic operators originating from mathematical physics. Using quantum graph model, we analyze the dispersion relati...

Carbon is an element with extremely versatile bonding properties and theoretical calculations have suggested the possible existence of several hundred structural allotropes. Many, or even most, these are predicted to be formed under conditions high pressure temperature. On other hand, experimental studies identified surprisingly few In this paper, physical transformations observed in experiment...
