Slow dynamics of disordered zigzag chain molecules in layered LiVS2 under electron irradiation

Abstract Electronic instabilities in transition metal compounds often spontaneously form orbital molecules, which consist of orbital-coupled metal ions at low temperature. Recent local structural studies utilizing the pair distribution function revealed that preformed orbital molecules appear disord...
