Figure 2
Evolution with pressure of the unit-cell parameters and volume of trigonal TiS2. Data are from Allan et al. (1998). The lines for a and c are the axial Birch–Murnaghan EoSs fitted to the data, and the black solid line is the volume variation calculated from these two EoSs. It is almost indistinguishable from the EoS fitted directly to the P–V data (red dashed line). |
