From the paper:
"The synthesis of silicene opens up interesting perspectives since silicene, with nontrivial electronic structure and a spin-orbit coupling of 1.55 meV that is much larger than that of graphene, is predicted to exhibit a quantum spin Hall effect in an accessible temperature regime. Moreover, silicene can more easily be integrated into current Si-based electronics compared to graphene."
In a nutshell, we know a heck of a lot more about using silicon for devices than carbon. So interfacing this with current silicon devices and making advances in understanding will likely occur more quickly.
- JoeAltmaier 15y agoBut we know almost nothing about the properties of this rarely-seen variant, silicene. Like graphene, it may exhibit wildly different responses than normal silicon. That paper simply repeats the same unsupported optimism as the puff piece - "can more easily be integrate" - really? How? Again, because of the name? Consider: if silicene ends up useful, it will be precisely because of how very different it is than current silicon forms. Integration challenges will revolve around manufacturing e.g. deposition and adhesion and a hundred other factors, none of which resemble normal silicon properties.
