  • We have used low-energy electron microscopy to investigate in real time the thermodynamically driven faceting of stepped Si(111) surfaces into (7×7) reconstructed (111) facets and «step bunches.» Our data are inconsistent with the thermodynamic expectation that an isolated linear facet should grow without limit: Instead we find that the width of the (7×7) reconstructed (111) facets quickly reaches a constant maximum size. We discuss the possibility that elastic relaxations caused by the facet… CONTINUE READING
