Motivated by the increasing use of InP in high speed opto-electronic devices that are fabricated using molecular beam epitaxy (MBE), the surface reconstruction phases of the technologically important InP(001) surface are studied. This study is performed in a combined ultrahigh vacuum MBE and scanning tunneling microscopy (STM) multi-chamber facility that incorporates a solid source phosphorus evaporation source and a novel temperature measurement system accurate to within ±2 @super o@C. Both reflect ion high energy electron diffraction (RHEED) and STM are used to map out the InP(001) surface reconstruction phase's dependence upon substrate temperature and phosphorus pressure. A c(4x4), a (2x1), and a (2x4)/c(2x8) reconstruction are all observed. Thi s work was funded in part by the National Science Foundation (DMR-9733994) and the Office of Naval Research (N00014-97-1-1058).
