“…One among interesting multicomponent GaSb-based systems is a quarternary Ga-Sb-Bi-Sn system. There are a lot of literature data concerning with the thermodynamics of its constituent binary systems Ga-Sb [1][2][3][4][5][6][7], Ga-Bi [8][9][10][11][12], Ga-Sn [13][14][15][16], Bi-Sb [17][18][19], Sb-Sn [20] and Bi-Sn [21], as well as for the ternaries Ga-Sb-Bi [8,[22][23][24], Ga-Sb-Sn [25,26], Ga-Bi-Sn [27] and Sb-Bi-Sn [28], while no references on thermodynamic behavior of quarternary Ga-Sb-Bi-Sn alloys are available up to now.…”
