Abstract

The microscopic structure of the P-rich (2 x 1)-like surfaces of InP(001) is investigated by sort X-ray photoemission spectroscopy (SXPS) and scanning tunneling microscopy (STM). The samples were grown by metal organic vaporphase epitaxy (MOVPE) and then transferred under ultra high vacuum (UHV) conditions to UHV analysis chambers. STM images show a P-rich as-grown surface after transfer and another less P-rich surface after prolonged annealingat 350 degrees C. The In4d emission line is not affected by the change in surface reconstruction and shows a small surface component shifted by 0.48 eV towards higher binding energies. The line shape of the P2p core level, on the other hand, changes: On the as-grown surface, one surface component which is shifted by 0.98 eV towards higher binding energies is found after transfer, whereas two surface components shifted to higher and lower bindingenergies, respectively, appear after annealing at 350 degrees C. These results are consistent with the structure models derived from STM for the different P-rich (2 x 1)-like surfaces. (C) 2000 Elsevier Science B.V. All rights reserved.
