These data were taken at room temperature, but thermal shifts of band edges in semiconductors are known to be sufficiently small, typically 10–3 eV/K (Ref. 4), that comparison with low-temperature theory is appropriate here. For example, E(X) at room temperature is 2.04 eV in InP.

    • Since the bond length in the rocksalt structure is larger than that in the zinc-blende structure
    • we used a larger muffin-tin radius for P in the former structure. This is necessary in order to compare total energies between the two different structures on the same footing. The muffin-tin radii for In were 2.50 aB, where aB is the hydrogenic Bohr radius; for P, the muffin-tin radii were chosen to be 1.80 aB for the zinc-blende structure and 2.20 aB for rocksalt, to reflect the larger In-P bond length.

    • Since thermal expansion and pressure corrections for the lattice constants have opposite signs
    • the difference between zero-pressure, zero-temperature and one-atmosphere, room-temperature lattice constants is commonly small: for example, in bulk Si the zero-temperature, zero-pressure bond length is 2.3508 A, compared with 2.3516 A at room temperature and one atmosphere pressure.
