Structural transformations of InP(001) surfaces over a wide range of temperature and surface stoichiometry have been investigated. (1 x 1)- and (2 x 1)-reconstructed surfaces are formed under phosphorus-rich conditions, which transform to a (2 x 4)-reconstructed form when annealed in vacuum at above 570 K. A new intermediate (2 x 2)/c(2 x 4) surface structure is identified during the transformation from (2 x 1)to(2 x 4). Both the (2 x 4)and the (2 x 2) forms of reconstruction are proposed to involve a first layer of mixed In-P dimers and a second layer consisting of 50% phosphorus and 50% indium.
