Resumen

The thermal conductivity (κ(T)) in a lattice is studied as a function of rigidity by using the Kubo-Greenwood formula. The rigidity is modulated by changing the second neighbour interactions. The results show that κ(T) is strongly determined by the rigid character of the network through the low frequency vibrational modes. The transition from an isostatic to overconstrained lattices is thus reflected in the behavior of κ(T).
