34. In the previous pseudopotential calculation in Ref. 8 (using a smaller plane-wave cutoff energy of 8 Ry) the reverse-buckled PC model appeared to be slightly (0.005 eV) higher in energy than the PC model. The energy difference is even smaller in the present study. This result calls more attention to the reverse-buckled PC model. Since the involved energy difference is too small, however, a decisive conclusion on the energetics would require a systematic examination as to whether the energy difference is affected by the use of different LDA schemes or more careful parametrizations of the correlation energy [see, for example, J. P. Perdew and Y. Wang, Phys. Rev. B 45, 13t244 (1992)].
