Ultrahigh Electron Thermal Conductivity in T-Graphene, Biphenylene, and Net-Graphene
nonhexagonal rings impacts the thermal conductivity of three 2D carbon allotropes: T-graphene (four and eight rings), biphenylene (four, six, and eight rings), and net-graphene (four, six, and eight rings), is [...] isolated nonhexagonal carbon rings in graphene are associated with strain relaxation and curvature, dense and ordered arrangements of four-, five-, and eight-membered rings with strained carbon–carbon bonds
