Spin-orbit coupling in hydrogenated graphene.
First-principles calculations of the spin-orbit coupling in graphene with hydrogen adatoms in dense and dilute limits are presented. The chemisorbed hydrogen induces a giant local enhancement of spin-orbit coupling due to sp(3) hybridization which depends strongly on the local lattice distortion. Guided by the reduced symmetry and the local structure of the induced dipole moments, we use group ...
متن کاملSpin Transport and Spin Precession in Graphene
Spin degree of freedom of electrons is one of the alternative state variables under consideration for processing information, beyond the charge based CMOS technology. The potential of spintronics based research lies in the possibilities for a new generation of computers that can be non-volatile, faster, smaller, and capable of simultaneous data storage and processing all with reduced energy con...
متن کاملSpin-Orbit Coupling Enhancement in Weakly Hydrogenated Graphene
Graphene holds considerable promise for novel applications in spintronics and quantum information processing because it has a high degree of electron mobility and gate tunability. Yet it also suffers from inherent drawbacks. For example, its lack of an energy band gap limits its capacity to be used in conventional charge-based semiconductor devices, and its extremely small spin-orbit (SO) inter...
متن کاملElectron transport, interaction and spin in graphene and graphene nanoribbons
Since the isolation of graphene in 2004, this novel material has become the major object of modern condensed matter physics. Despite of enormous research activity in this field, there are still a number of fundamental phenomena that remain unexplained and challenge researchers for further investigations. Moreover, due to its unique electronic properties, graphene is considered as a promising ca...
متن کاملSpin transport in rough graphene nanoribbons
We investigate spin conductance in zigzag graphene nanoribbons and propose a spin injection method based only on graphene. Combining density functional theory with tight-binding transport calculations, we find that nanoribbons with asymmetrically shaped edges show a non-zero spin conductance and can be used for spin injection. Furthermore, nanoribbons with rough edges exhibit mesoscopic spin co...
