摘要
The sublimation energy, lattice constants, and bulk modulus of a periodic model of the common phase of ice, Ih, vary dramatically when calculated with several commonly employed approximations to the electron exchange-correlation energy functional. Several gradient-corrected functionals give accurate descriptions of this hydrogen-bonded material.
