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…
Transition of Graphene on a Substrate to a Semimetallic State
P. V. Ratnikov
Graphene on a substrate has been shown to exhibit a transition, depending on the substrate material, from a zero-gap semiconductor state to a semimetallic state. The ground-state e…
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)…
