Abstract |
|
|
|
Strains are essentially change the electronic, mechanical and thermodynamic properties of materials.
The mechanical response of graphene-based nano-ribbons has been investigated in this paper:
we treated the mechanical strength and properties of single ribbons formed by hexagonally-arranged
covalently bonded carbon atoms under tension test as a function of size. Our results indicate that
strain of ribbon’s bulk with added molecules under tension can have a significant dependence on the
polarization. We show that it is possible to modulate the saturated graphene-based ribbon energy
gap value. Proposed structures could become of great use for possible realizations pursuing make
the graphene-based ribbons tunable.
