“…Finally, we present the details of the semi-infinite surface Green's function calculations used to predict topological surface features for the materials in the main text. All of the materials candidates presented in this work were previously synthesized, and all were sufficiently stable as to have been powderized and examined under X-ray diffraction in an argon environment [43][44][45][46][47]49 .…”

Materials whose gapless surface states are protected by crystal symmetries include mirror topological crystalline insulators and nonsymmorphic hourglass insulators. There exists only a very limited set of possible surface crystal symmetries, captured by the 17 "wallpaper groups." Here we show that a consideration of symmetry-allowed band degeneracies in the wallpaper groups can be used to understand previously described topological crystalline insulators and to predict phenomenologically distinct examples. In particular, the two wallpaper groups with multiple glide lines, and4, allow for a topological insulating phase whose surface spectrum consists of only a single, fourfold-degenerate, true Dirac fermion, representing an exception to a symmetry-enhanced fermion-doubling theorem. We theoretically predict the presence of this phase in SrPb in space group 127 (4.

“…Fig. 6 shows the calculated formation enthalpies (DH) compared with their shear modulus and melting temperatures (T m ) of Ca 2 Pb, Sr 2 Pb and Ba 2 Pb compounds [6][7][8][9][10]. It is interesting to note that, for these Zintl compounds, the formation enthalpy is more negative if the compound has a higher melting temperature and a larger shear modulus.…”

“…The ground-state electronic band structures, Boltzmann transport and bulk moduli of these three alkaline earth compounds Ca 2 Pb, Sr 2 Pb and Ba 2 Pb have been calculated using density functional theory [5]. The congruent melt points for Ca 2 Pb, Sr 2 Pb, and Ba 2 Pb are 1476 K, 1428 K, and 1201 K, respectively [6][7][8][9][10]. The Ca 2 Pb with a direct band gap has been extensively investigated because of its unique semiconductor property [7,11].…”

“…Ca, Sr, Ba; B = IVb element = Si, Ge, Sn, Pb). For this purpose, we carried out a brief survey on the recent results of thermodynamic modeling [26][27][28][34][35][36][37][38][39][40][41][42] and rather scarce results of direct calorimetric measurements of the enthalpies of mixing of the liquid A-B alloys. [43][44][45][46][47][48][49][50] For the phase diagrams, we analyzed the general pictures focusing on the characteristic temperatures of melting of the simplest compounds (A 2 B, AB, AB 2 ), temperatures and compositions of A-and B-rich eutectics (Tables 6, 7).…”

Mixing enthalpies of the liquid alloys in the binary Ca-Ge system were measured by isoperibolic solution calorimetry within the concentration ranges 0 < x Ge < 0.08 at 1270-1300 K, and 0.54 < x Ge < 1 at 1370-1520 K. The experimental data show great exothermic effects of alloy formation; the partial mixing enthalpies at infinite dilution of the components are DH 1 Ca = 2138 to 2140 kJ mol 21 and DH 1 Ge = 2200 kJ mol 21 (at 1300 K). The Gibbs energies and entropies of mixing, activities of the components, and molar fractions of associates in the melts were calculated over a wide temperature range, using models of ideal and regular associated solutions, according to the data in literature for the thermodynamic properties of solid alloys and the phase diagram of the Ca-Ge system.
