Light metal decorated graphdiyne nanosheets for reversible hydrogen storage

2018-06-20T14:33:33+00:00 June 20th, 2018|Categories: Publications|Tags: |

The sensitive nature of molecular hydrogen (H 2 ) interaction with the surfaces of pristine and functionalized nanostructures, especially two-dimensional materials, has been a subject of debate for a while now. An accurate approximation of the H 2 adsorption mechanism has vital significance for fields such as H 2 storage applications. Owing to the importance of this issue, we have performed a comprehensive density functional theory (DFT) study by means of several different approximations to investigate the structural, electronic, charge transfer and energy storage properties of pristine and functionalized graphdiyne (GDY) nanosheets. The dopants considered here include the light metals Li, Na, K, Ca, Sc and Ti, which have a uniform distribution over GDY even at high doping concentration due to their strong binding and charge transfer mechanism. Upon 11% of metal functionalization, GDY changes into a metallic state from being a small band-gap semicond…

From Klein to anti-Klein tunneling in graphene tuning the Rashba spin-orbit interaction or the bilayer coupling. (arXiv:1806.06962v1 [cond-mat.mes-hall])

2018-06-20T04:30:23+00:00 June 20th, 2018|Categories: Publications|Tags: |

We calculate the transmission coefficient through a potential barrier in monolayer graphene with Rashba spin-orbit coupling and in bilayer graphene. We show that in both the cases one can go from Klein tunneling regime, characterized by perfect normal transmission, to anti-Klein tunneling regime, with perfect normal reflection, by tuning the Rashba spin-orbit coupling for a monolayer or the interplane coupling for a bilayer graphene. We show that the intermediate regime is characterized by a non-monotonic behavior of the transmission amplitude.
