Description:
Author(s): Joseph T. Schick and Andrew M. Rappe We study negative thermal expansion (NTE) in model lattices with multiple atoms per cell and first- and second-nearest neighbor interactions using the (anharmonic) Morse potential. By exploring the phase space of neighbor distances and thermal expansion rates of the bonds, we determine the condition… [Phys. Rev. B 93, 214304] Published Tue Jun 07, 2016
