Journal ArticleDOI
Ferromagnetism in Semihydrogenated Graphene Sheet
TL;DR: Using density functional theory, it is shown that when half of the hydrogen in this graphane sheet is removed, the resulting semihydrogenated graphene becomes a ferromagnetic semiconductor with a small indirect gap.
Journal ArticleDOI
Clustering of Ti on a C60 surface and its effect on hydrogen storage
TL;DR: Using first-principles calculations based on density functional theory, it is shown that Ti atoms would prefer to cluster on the C60 surface, which can significantly alter the nature of hydrogen bonding, thus affecting not only the amount of stored hydrogen but also their thermodynamics and kinetics.
Journal ArticleDOI

TL;DR: This study has successfully grown predominantly monolayer MoS2 on an inert and nearly lattice-matching mica substrate by using a low-pressure chemical vapor deposition method, and the homogeneously strained high-quality monolayers prepared in this study could competitively be exploited for a variety of future applications.
Journal ArticleDOI
First-principles study of hydrogen storage on Li12C60
TL;DR: Using density functional theory, it is found that an isolated Li(12)C(60) cluster where Li atoms are capped onto the pentagonal faces of the fullerene not only is very stable but also can store up to 120 hydrogen atoms in molecular form with a binding energy of 0.075 eV/H(2).
Journal ArticleDOI
Structures and Phase Transition of a MoS2 Monolayer
TL;DR: Using first-principle calculations combined with Boltzmann transport equation, Wang et al. as mentioned in this paper have extensively studied the geometry, energetics, electronic structure, optical absorption, and carrier mobility of various phases of MoS2.
