Dependence of nonthermal metallization kinetics on bond ionicity of compounds

phonon hardening in the bulk. Here we study how ionic bonds react to electronic excitation. Density- functional molecular dynamic predicts that ionic crystals may melt depends on a bonding type: it is harder to co...

The Mixed-Valence Catena-Heteropolycation (Bi2S2)(+)

The reaction of Bi and Bi2S3 in the Lewis-acidic ionic liquid [BMIm]Cl . 4.3AlCl(3) (BMIm=1-n-butyl-3-methylimidazolium) at 200 degrees C yielded air-sensitive-Bi bonds. The assignment of bonds is ambiguous as a distinction...
