    "abstract": "Structure of the Ga-stabilized GaAs(001)-c(8x2) surface has been studied\nusing rocking-curve analysis of reflection high-energy electron diffraction\n(RHEED). The c(8x2) structure emerges at temperatures higher than 600C, but is\nunstable with respect to the change to the (2x6)/(3x6) structure at lower\ntemperatures. Our RHEED rocking-curve analysis at high temperatures revealed\nthat the c(8x2) surface has the structure which is basically the same as that\nrecently proposed by Kumpf et al. [Phys. Rev. Lett. 86, 3586 (2001)]. We found\nthat the surface atomic configurations are locally fluctuated at high\ntemperatures without disturbing the c(8x2) periodicity.",
