# Quantum spin Hall effect on germanene nanorod embedded in completely hydrogenated germanene

@article{Seixas2014QuantumSH, title={Quantum spin Hall effect on germanene nanorod embedded in completely hydrogenated germanene}, author={Leandro Seixas and Jos{\'e} Eduardo Padilha and Adalberto Fazzio}, journal={Physical Review B}, year={2014}, volume={89}, pages={195403} }

We show that germanene nanoroads embedded in completely hydrogenated germanene (germanane) exhibits a quantum spin Hall effect (QSHE). These nanoroads can be obtained experimentally by local hydrogen dissociation from germanane. Using first-principle calculations we predict that germanene nanoroads with zigzag interfaces show dissipationless conducting channels with in-plane and out-of-plane spin textures.
