Effect of anisotropy on the logarithmic singularities in the electronic density of states in layered systems
The electronic density of states was calculated for the case of anisotropic dispersion law of electrons. The obtained density can have one or two logarithmic singularities. Number of singularities, as well as the distance between them, depends on two parameters contained in the dispersion law fo...

| Sumario: | The electronic density of states was calculated for the case of anisotropic dispersion law
of electrons. The obtained density can have one or two logarithmic singularities. Number of
singularities, as well as the distance between them, depends on two parameters contained in
the dispersion law for electrons. |
