Graphdiyne nanomaterials are low density and highly porous carbon-based two-dimensional (2D) materials, with outstanding application prospects for electronic energy storage/conversion systems. In two latest scientific advances, large-area pyrenyl graphdiyne (Pyr-GDY) pyrazinoquinoxaline (PQ-GDY) nanosheets have been successfully fabricated. As the first theoretical study, herein we conduct firs...
Semiconducting single-walled carbon nanotubes (s-SWNTs) are regarded as an important candidate for infrared (IR) optical detection due to their excellent intrinsic properties. However, the strong binding energy of excitons in s-SWNTs seriously impedes the development of s-SWNTs IR photodetector. This Communication reports an IR photodetector with highly pure s-SWNTs and γ-graphdiyne. The hetero...
Higher-order topological insulators have attracted great research interest recently. Different from conventional insulators, higher-order do not necessarily require spin-orbit coupling, which makes it possible to realize them in spinless systems. Here, we study phonons 2D graphyne family materials. By using first-principle calculations and topology/symmetry analysis, find that both graphdiyne $...
Adsorption of hydrogen on graphdiyne (GDY) and boron-graphdiyne (BGDY) doped with palladium clusters has been investigated by performing density functional calculations. Pd6 fits well the large holes those porous layers, preserving its octahedral structure in GDY changing it to a capped trigonal bipyramid BGDY. Pd6GDY adsorbs up five H2 molecules sizable adsorption energies, two dissociated thr...
