Electronic structure of silicon-based nanostructures

We have developed a unifying tight-binding Hamiltonian that can account for the electronic properties of recently proposed Si-based nanostructures, namely, Si graphene-like sheets and Si nanotubes. We considered the $s{p}^{3}{s}^{*}$ and $s{p}^{3}$ models up to first- and second-nearest neighbors, r... View More
