▎ 摘 要
Using quantum mechanical approaches, the electronic and electrophysical properties of T-contact connections based on thin chiral single-walled carbon nanotubes (SWCNTs) and graphene zigzag nanoribbons are studied from the standpoint of their application as field-emission blade-type nanoemitters with an atomic thickness of the emitting blade. The fact of a sharp decrease in the contact electrical resistance by 87% for the investigated three-pole contact (T-contact) from the side of two contacts, which are semi-infinite SWCNTs, is established. Resistance of a graphene zigzag nanoribbon connected perpendicular to the contacts from SWCNTs as part of a three-pole is comparable to the resistance of the nanoribbon itself and is similar to 3.3 k Omega. It is shown that the covalent bonds of graphene ribbons with nanotubes predetermine a high tensile strength in strong electric fields, which ensures the integrity of the atomic structure even in electric fields of similar to 1.5 x 10(8) V/nm. It was revealed that the mechanical force of the electric field, which is from 23 to 36 nN, causes periodic deformations of the atomic frame with a frequency of similar to 1.25 THz.
