Tetragraphene is a theoretically predicted quasi-2D carbon allotrope
featuring a combination of square and hexagonal rings. This material is
semiconducting and presents highly anisotropic electronic properties.
Motivated by the fact that quasi-1D nanocarbon systems can present
properties remarkably different from their 2D counterparts, we propose
to study tetragraphene-based nanoribbons and investigate their stability
and their electronic and magnetic properties using quantum-based
computational methods. We show how the electronic structure of these
tetragraphene nanoribbons (TGNRs) depends on chirality, width, and the
details of edge reconstruction. We predict the existence of different
hybridization states at the edges of these systems, thus demonstrating a
set of versatile electronic behaviors. In particular, edge hybridization
is found to induce band gap modulation, as well as the emergence of
magnetic edge states. Our results suggest that TGNRs can be prototypes
for future applications in nanoelectronics.
