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.

Direct Evidence of Dirac Signature in Bilayer Germanene Islands on Cu(111)
TLDR
Structural and electronic characterizations as well as theoretical calculations unequivocally demonstrate for the first time the presence of a nearly linear energy dispersion in the vicinity of the Fermi energy, as expected of the Dirac signature for theoretical freestanding germanene.
Quantum spin Hall states in graphene interacting with WS2 or WSe2
In the framework of first-principles calculations, we investigate the structural and electronic properties of graphene in contact with as well as sandwiched between WS2 and WSe2 monolayers. We report…
Electric Control of the Edge Magnetization in Zigzag Stanene Nanoribbons from First Principles
To learn how best to manipulate spin states in low-dimensional structures, the authors use density functional theory to study the magnetism at the edges of nanoribbons of stanene (think graphene, but…
Continuous germanene layer on Al(111).
TLDR
Germanene, a 2D honeycomb structure similar to silicene, has been fabricated on Al(111) and first-principles calculations indicate that the Ge atoms accommodate in a very regular atomic configuration with a buckled conformation.
Germanium, carbon‐germanium, and silicon‐germanium triangulenes
TLDR
A series of germanium‐containing triangular molecules have been studied by density functional theory (DFT) calculations and the compounds bearing more electronegative atoms in a‐positions of the triangular networks possess higher aromatic character and stronger ferromagnetic ordering.
Tip-Induced Switch of Germanene Atomic Structure.
TLDR
It is found that germanene can crystallize in two stable but different structures when grown on Al(111) at the same temperature.
Germanene: the germanium analogue of graphene.
TLDR
A topical review of the various methods to synthesize germanene is addressed, a brief overview of the key results that have been obtained by density functional theory calculations are provided and the potential of germanenes for future applications is discussed.
Highly Conductive Metallic State and Strong Spin–Orbit Interaction in Annealed Germanane
TLDR
A highly conductive metallic state in thermally annealed germanane (hydrogen-terminated germanene, GeH), which shows a resistivity of ∼10–7 Ω·m that is orders of magnitude lower than any other allotrope of germanium is reported.
First principles calculation of electronic, phonon and thermal properties of hydrogenated germanene
Germanene is a basic building block of two-dimensional materials of germanium and it exhibits many unique electronic properties. It is necessary for germanene to tuning its electronic band structure…
Chemically functionalized germanene for spintronic devices: a first-principles study.
TLDR
It is proposed that a spin-valve nanodevice with a giant magnetoresistance of up to 10(7)% can be obtained from the semi-methylated germanene nanostructure by introducing an achievable magnetic field to stabilize its metal-like ferromagnetic state.
