Nitrogenated holey two-dimensional structures
Recent graphene research has triggered enormous interest in new two-dimensional ordered crystals constructed by the inclusion of elements other than carbon for bandgap opening. The design of new multifunctional two-dimensional materials with proper bandgap has become an important challenge. Here we report a layered two-dimensional network structure that possesses evenly distributed holes and ni...
متن کاملNitrogenated, phosphorated and arsenicated monolayer holey graphenes.
Motivated by a recent experiment that reported the synthesis of a new 2D material nitrogenated holey graphene (C2N) [Mahmood et al., Nat. Commun., 2015, 6, 6486], the electronic, magnetic, and mechanical properties of nitrogenated (C2N), phosphorated (C2P) and arsenicated (C2As) monolayer holey graphene structures are investigated using first-principles calculations. Our total energy calculatio...
متن کاملExotic thermoelectric behavior in nitrogenated holey graphene
Combining first-principles approaches with the Boltzmann transport equation and semi-classical analysis we investigate the thermal conductivity k, thermopower S, electrical conductivity s, and carrier mobility m of newly synthesized nitrogenated holey graphene (NHG). Strikingly, the NHG possesses exceedingly high S and s but a fairly low lattice thermal conductivity kL, and therefore extraordin...
متن کاملHoley two-dimensional transition metal oxide nanosheets for efficient energy storage
Transition metal oxide nanomaterials are promising electrodes for alkali-ion batteries owing to their distinct reaction mechanism, abundant active sites and shortened ion diffusion distance. However, detailed conversion reaction processes in terms of the oxidation state evolution and chemical/mechanical stability of the electrodes are still poorly understood. Herein we explore a general synthet...
متن کاملTwo- and Three-Dimensional Holey Phononic Crystals with Unit Cells of Resonators
Introduction: a lot of studies have been devoted on the propagation behaviors of the elastic waves in phononic crystals (PCs). These new artificial structures exhibit bandgaps in their spectra where the propagation of waves is fully prohibited. The bandgaps in PCs may have potential applications in acoustic isolation, noise suppression, vibration attenuation, etc. Much reported work is focused ...
