Abstract
Recent advances in the high pressure researches of the structure of liquid metals and liquid semiconductors are reviewed. In the liquid metals and liquid semiconductors, electrons spread over the whole liquids and play an important role on the interaction between atoms, which strongly depends on the electron density. The pressure dependence of the local structure of liquids is found to be different from that of crystals. Results of the static structure factor of liquids, S(Q) and the pair distribution function, g(r) for liquid alkali metals, liquid halogen, liquid chalcogen, liquid group 15 elements, liquid IV-VI compounds, liquid group 14 elements and liquid III-V, II-VI, I-VII compounds are discussed in relation to the bonds between atoms.
