Ultrahigh Electron Thermal Conductivity in T-Graphene, Biphenylene, and Net-Graphene
al 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 [...] approaches the values of pristine graphene. 2D carbon allotropes could be of interest for applications requiring thermal energy transfer by a combination of diffusion of electrons and phonon vibrations. © The
