Silicon dioxide is fundamental in geology, in the electronic materials industry, and in the glass industry. We have carried out an ab initio total-energy minimization study of the structure and bonding of alpha cristobalite using nonlocal pseudopotentials in a Car-Parrinello-type molecular-dynamical method. The electronic energy is expressed in the local-density approximation. The use of a separable nonlocal pseudopotential preserves the O(MlnM) scaling of the computation for M plane waves. The resulting theoretically computed minimum-energy structure agrees well with experiment.
