摘要：

We report on a full potential linear muffin-tin orbital (FPLMTO) as well as pseudopotential calculation of the electronic structure of CO2 at ambient conditions as well as under high pressure. The calculations support the experimentally observed pressure induced phase transition. We have also calculated the bulk modulus of different high pressure phases. At even higher pressures, we predict the transition to a very hard phase of the Stishovite type.
