Elektronová struktura slitin india a cínu

Abstract

The In-Sn system is interesting due to the existence of the simple hexagonal (sh) structure for compositions from 75 to 87 at% Sn at 25 ºC and from 73 to 85 at% Sn at -150 ºC. These alloys are usually referred to as gamma-Sn. Here we study the electronic structure and total energy of gamma-Sn with the help of virtual crystal approximation and demonstrate that sh structure has the lowest energy in the interval of existence of gamma-tin
