Structurally complex Frank-Kasper phases and quasicrystal approximants: electronic origin of stability
Valentina F Degtyareva, Natalia S Afonikova
Metal crystals with tetrahedral packing are known as Frank-Kasper phases with large unit cells with the number of atoms from hundreds to thousands. The main factors of the formatio…
Electron core ionization in compressed alkali metal cesium
V F Degtyareva
Elements of group I in the Periodic table have valence electrons of s-type and are usually considered as simple metals. Crystal structures of these elements at ambient pressure are…
Electronic origin of melting T-P curves of alkali metals with negative slope and minimum
Valentina F. Degtyareva
Group I elements - alkali metals Li, Na, K, Rb and Cs - are examples of simple metals with one s electron in the valence band. Under pressure these elements display unusually compl…
Complex structures of dense lithium: electronic origin
Valentina Degtyareva
Lithium - the lightest alkali metal - exhibits unexpected structures and electronic behaviour at high pressures. As the heavier alkalis, Li is bcc at ambient pressure and transform…
Incommensurate host-guest structures in compressed elements: Hume-Rothery effects as origin
Valentina F Degtyareva
Discovery of the incommensurate structure in the element Ba under pressure 15 years ago was followed by findings of a series of similar structures in other compressed elements. Inc…
Complex structures in the Au-Cd alloy system: Hume-Rothery mechanism as origin
Valentina F. Degtyareva, Nataliya S. Afonikova
The binary (simple metal) phase diagram Au-Cd contains a number of intermetallic compounds with various distortions, superlattices and vacancies. To understand the reasons of these…
