Abstract

The structural phase diagram of the hydrogen terminated diamond-(111) surface, which is of considerable relevance with regard to the low-pressure synthesis of diamond, has been investigated by the highly surface sensitive technique of thermal energy helium atom scattering. A new phase with a (2 × 1) symmetry has been observed to occur upon heating above 940 K, significantly below the well known transition to the hydrogen-free (2 × 1) π-bonded chain structure at 1250 K. It is proposed that the new phase consists of a hydrogen (2 × 1) overlayer on an unreconstructed (1 × 1) diamond substrate. Structural models for this new phase will be presented.
