Thermal conductivity κ of rough-edge nanoribbon versus temperature for ribbon length of N = 500 unit cells. Thermal conductivity κ of rough-edge nanoribbon (ribbon width K = 18 atomic chains, rough edges widths K1 = 4 atomic chains, porosity of rough edges p = 0.20) versus temperature T for ribbon length of N = 500 unit cells of the two-dimensional diamond-like lattice of Ge (blue circles, line 1) or Si (red diamonds, line 2) atoms.
