Niladri Sekhar Mondal et al.

Summary: The mechanical and electronic properties of non-hexagonal two-dimensional tetragonal-silicene (TS) were investigated using first-principle and tight-binding (TB) calculation methods. The study found two Dirac cones in TS, with strong stability and robustness under a wide range of hopping parameters. Additionally, the presence of a spin-orbit bandgap larger than silicene was observed, demonstrating the potential for TS in nano-electronic applications.
