Title: Massless Fermions in multilayer graphitic systems with misoriented layers.

Abstract

We examine how the misorientation of a few stacked graphene layers affects the electronic structure of carbon nanosystems. We present ab initio calculations on bilayer and trilayer systems to demonstrate that the massless fermion behavior typical of single-layered graphene is also found in incommensurate multilayered graphitic systems. We also investigate the consequences of this property on experimental fingerprints, such as Raman spectroscopy and scanning tunneling microscopy (STM). Our simulations reveal that STM images of turbostratic few-layer graphite are sensitive to the layer arrangement. We also predict that the resonant Raman signals of graphitic samples are more sensitive to the orientation of the layers than to their number.

  • The influence of substrate misorientation on the structure and morphology of In[sub 0.2]Ga[sub 0.8]As layers grown by molecular beam epitaxy on vicinal, near (001), GaAs substrates was investigated by transmission electron microscopy. The substrates were tilted at angles between 0[degree] and 10[degree] in [l angle]100[r angle], [l angle]110[r angle], and [l angle]120[r angle] directions. In layers which exceeded the critical thickness, networks of 60[degree] dislocations running along the intersections of the four [l brace]111[r brace] planes with the interface were observed. Growth uniformity and anisotropy of strain relaxation were shown to depend on the type of growth steps introduced bymore » a particular tilting direction.« less
  • Kaluza-Klein model on M{sup 4} {times} S{sup 1} with SU(N) gauge fields and N{sub f} fermions in fundamental representation is considered. It is noted that on one-loop level the lowest state of this theory corresponds to effective four-dimensional theory which has no massless fermions. This statement does not depend on fermion boundary conditions. The state with massless four-dimensional fermions is metastable. In this paper it is shown that this metastable states can be stabilized by effects of classical gravitation. The same problem of metastability of states with zero fermionic modes can appear in more realistic superstring compactification models and thesemore » effects of classical gravitation can resolve this problem of metastability.« less
  • The three-dimensional gravitational effective action due to a massless fermion coupled to a weak gravitational field is calculated. Radiative corrections induce the parity-violating gravitational Chern-Simons term.
  • A pure Kaluza--Klein theory contains no massless fermion in four-dimensional theory. We investigate the effect of introducing torsion on the internal manifold and find that there are massless fermions. The hope is that given an isometry group the representation to which these fermions belong is fixed, in contrast to the situation in Yang--Mills theory. We show that this is indeed the case, but the representations do not appear to be the ones favored by current theoretical prejudice. The cases with parallelizable torsions on a group manifold as the internal manifold are analyzed in detail.
  • The interaction of the S=1/2 fermion field with the 2(2S+1)- component massless field is considered. New interpretation of the bispinors corresponding to the S=1 particles is proposed. The equation analogous to the Dirac oscillator is obtained. 13 refs.
