The first clear atomic-scale images of a Ni2P(0001) surface have been obtained by means of a scanning tunneling (STM) microscope. The STM image shows an ordered hexagonal syrninctry of the (0001) face, which can be assigned to phosphorus atoms on Ni3P1- and Ni3P2-terminated Surface. The high temperature annealing is crucial to get a well-ordered atomic structure.
