Abstract

We present phase diagram of materials (Silicon, Carbon, and Titanium disilicide TiSi₂) obtained by the first principles and semi-empirical free-energy calculations. Phase boundary of the two solid phases of TiSi₂ was found to sensitively depend on the pressure, which explains the suppressed phase transition in the thin films where the interfacial stress is large. The Clapeyron slope of the graphite-liquid phase boundary was found to rather suddenly decrease at about 1 GPa because of the change in the liquid structure. The structural change is continuous, but becomes first-order like only at lower temperature range where the liquid is metastable.
