We perform a quantitative analysis based on local-spin density functional theory. The agreement between theoretical and experimental results is good, and the phase transitions are well reproduced.8 p.application/pdfeng(c) The American Physical Society, 2003Transformacions de fase (Física estadística)Teoria del funcional de densitatSemiconductorsPhase transformations (Statistical physics)Density functional theorySemiconductorsinfo:eu-repo/semantics/article507930info:eu-repo/semantics/openAccess
