Framework flexibility and the negative thermal expansion mechanism of copper(I) oxide Cu2O
The negative thermal expansion (NTE) mechanism in Cu2O has been characterized via mapping of different Cu2O structural flexibility models onto phonons obtained using ab initio lattice dynamics. Low-frequency acoustic modes that are responsible for the NTE in this material correspond to vibrations of...
