Quantum Well Based on Graphene and Narrow-Gap Semiconductors
P. V. Ratnikov, A. P. Silin
We consider the energy spectrum of the planar quantum well which consisted of two ribbons of narrow-gap semiconductors and a graphene ribbon between ones. It is shown that the gapl…

Planar Heterostructure Graphene -- Narrow-Gap Semiconductor -- Graphene
P. V. Ratnikov, A. P. Silin
We investigate a planar heterostructure composed of two graphene films separated by a narrow-gap semiconductor ribbon. We show that there is no the Klein paradox when the Dirac poi…

Ground State Energy of Current Carriers in Graphene
P. V. Ratnikov, A. P. Silin
The ground state energy of current carriers in graphene considered as a zero-gap semiconductor was calculated in the two-band approximation. The condition of the electronic (hole)…
